We have studied the equation of state (EOS) and the contribution of partial waves for symmetric nuclear matter (SNM) and pure neutron matter (PNM) to explain the effect of Pauli operator treatment. Our calculations have been carried out in the framework of Bruckner-Hartree-Fock (BHF) approach with angle average approximation and exact Pauli operato...

The binding energy per nucleon for nuclear matter, i.e., equation of state (EOS), within the Brueckner–Hartree–Fock (BHF) approach with the consideration of various three-body forces (3BFs) like the phenomenological 3BF and by adding a contact term to the BHF calculations are considered at variance densities. The 3BF contribution turns out to be no...

Full-text available
A self-consistent Green’s Function approach is used to study the influence of short-range correlations beyond the mean-field approach of nuclear matter. The ladder equation, including both particle-particle and hole-hole propagation, is solved in nuclear matter for a realistic interaction derived from the CD-Bonn potential. The hole-hole interactio...
Article
Motivated by the recent measurements from the VEPP-3 electron storage ring, we investigate the tensor target polarization asymmetries T2M (M = 0, 1, 2) in the reaction γd → π⁰d with a particular interest in the effect of the intermediate ηNN three-body approach. This approach is based on realistic separable representations of the driving two-body i...
Article
Tensor target spin asymmetries T2M (M=0,1,2) in the reaction γd → π-pp are studied for photon energies from π-threshold up to 1.5GeV with inclusion of rescattering effects. It is shown that the influence of rescattering effects on the tensor target spin asymmetries is sizable in the energy region near π-threshold. At higher energies, much smaller i...
Article
The single-particle potentials and other properties at absolute zero temperature in isospin asymmetric nuclear matter are investigated in the frame of an extended Brueckner theory. Also thermal quantities are calculated in asymmetric nuclear matter using CD-Bonn potential and the Urbana three-body forces (3BF). Also, the effects of the hole–hole co...
Article
Microscopically, the equation of state (EOS) and other properties of asymmetric nuclear matter at zero temperature have been investigated extensively by adopting the non-relativistic Brueckner-Hartree-Fock (BHF) and the extended BHF approaches by using the self-consistent Green’s function approach or by including a phenomenological three-body force...
Article
The Equation of State (EOS) of pure neutron matter at zero temperature is calculated up to five saturation densities within the Brueckner theory with the inclusion of three-body forces. Three different realistic and accurate two-body forces are considered to evaluate the G-matrix effective interaction for nuclear matter. These models are the chiral...
Article
We have studied the single-particle properties and the equation of state (EOS) of symmetric nuclear and neutron matter within the framework of the Brueckner-Hartree-Fock (BHF) approach extended by including a phenomenological three-body force (3BF). Adding the 3BF to the initial two-body force (2BF) and applying a partial-wave expansion, G-matrix c...
Article
We study the properties of symmetric nuclear matter and pure neutron matter at zero temperature within the framework of the Brueckner theory using tabulated values of effective masses and depth of the single-particle energies. These tabulated values are chosen according to the work of Hassaneen et al, 2011. The Brueckner–Hartree–Fock approximation...

The equation of state (EOS) of symmetric nuclear and pure neutron matter has been investigated extensively by adopting the non-relativistic Brueckner-Hartree-Fock (BHF). For more comparison, the extended BHF approaches using the self-consistent Green’s function approach or by including a three-body force will be done. The EOS will be studied for di...
Article
Full-text available
The properties of nuclear matter are studied in the frame of the Brueckner theory. The Brueckner– Hartree–Fock approximation plus two-body density-dependent Skyrme potential which is equivalent to three-body interaction are used. Various modern nucleon–nucleon potentials are used in the framework of the Brueckner–Hartree–Fock approximation, e.g.: C...
Article
The microscopic and bulk properties of nuclear matter at zero and finite temperatures are studied in the frame of the Brueckner theory. The results for the symmetry energy are also obtained using different potentials. The calculations are based on realistic nucleon-nucleon interactions which reproduce the nucleon-nucleon phase shifts. These microsc...
Article
The properties of nuclear matter at zero and finite temperatures in the frame of the Brueckner theory realistic nucleon-nucleon potentials are studied. Comparison with other calculations is made. In addition we present results for the symmetry energy obtained with different potentials, which is of great importance in astrophysical calculation. Prop...
Article
We study the equation of state (EOS) of symmetric nuclear and neutron matter within the framework of the Brueck-ner-Hartree-Fock (BHF) approach which is extended by including a density-dependent contact interaction to achieve the empirical saturation property of symmetric nuclear matter. This method is shown to affect significantly the nuclear matt...
Article
Full-text available
Symmetric nuclear matter is studied within the Brueckner-Hartree-Fock (BHF) approach and is extending to the self-consistent Green’s function (SCGF) approach. Both approximations are based on realistic nucleon-nucleon interaction; that is, CD-Bonn potential is chosen. The single-particle energy and the equation of state (EOS) are studied. The Fermi...
Article
Results of cold and hot symmetric nuclear matter and pure neutron matter calculations are presented. The Brueckner-Hartree-Fock (BHF) approximation + two body density dependent Skyrme potential which is equivalent to three body interaction are used. Various modern nucleon-nucleon (NN) potentials are used in the framework of BHF approximation , e.g....
Article
The binding energy of nuclear matter at zero temperature in the Brueckner–Hartree–Fock approximation with modern nucleon–nucleon potentials is studied. Both the standard and continuous choices of single particle energies are used. These modern nucleon–nucleon potentials fit the deuteron properties and are phase shifts equivalent. Comparison with ot...
Article
Full-text available
The one-body potentials for protons and neutrons are obtained from the self-consistent Green-function calculations of asymmetric nuclear matter, in particular their dependence on the degree of proton/neutron asymmetry. Results of the binding energy per nucleon as a function of the density and asymmetry parameter are presented for the self-consisten...

Properties of asymmetric nuclear matter are derived from various many-body approaches. This includes phenomenological ones like the Skyrme Hartree-Fock and relativistic mean field approaches, which are adjusted to fit properties of nuclei, as well as more microscopic attempts like the Brueckner-Hartree-Fock approximation, a self-consistent Greens f...

Article
In this paper we have reported the study of symmetry energy within the self-consistent Green-function approach. For the sake of comparison, the same calculations are performed using Brueckner-Hartree-Fock approximation. The symmetry energy is calculated for different densities and discussed in comparison with other predictions. The self-consistent...
Article
The properties of asymmetric nuclear matter have been investigated in the framework of the self-consistent Green function approach at zero temperature. Results of the total energy per nucleon as a function of the density and asymmetry parameter are presented for two modern realistic nucleon–nucleon interactions: Nijmegen II and CD-Bonn. For compari...
Thesis
Full-text available
Studies on the structure of nuclear systems are performed, ~which are based on realistic nucleon-nucleon interactions. Such realistic interactions induce two-body correlations in the nuclear many-body wave function. In particular one finds deviations of the single-particle Green's function from the mean field prediction of a Hartree-Fock theory. Su...
Article
Full-text available
The self-energy of nucleons in asymmetric nuclear matter is evaluated employing different realistic models for the nucleon-nucleon interaction. Starting from the Brueckner Hartree Fock approximation without the usual angle-average in the two-nucleon propagator the effects of the hole-hole contributions are investigated within the self-consistent Gr...
Article
Full-text available
The nuclear spectral function at high missing energies and momenta has been determined from a self-consistent calculation of the Green's function in nuclear matter using realistic nucleon-nucleon interactions. The results are compared with recent experimental data derived from ($e,e'p$) reactions on $^{12}C$. A rather good agreement is obtained if...
Thesis
We investigated the argument of recent publications that the good description of the nucleon-nucleon NN interaction at short distances by quark models is at present only qualitative. The quark model is simulated at short distances by a repulsive short range nonlocality. For larger radii, the one pion exchange potential OPEP is used. We found that t...
