  ABSTRACT: Optical potentials for the scattering of K+ from the 12C nucleus are calculated using the folding model. Angular distributions of the elastic and inelastic scattering differential cross sections at 635, 715, and 800 MeV/c are successfully described using these potentials. Good fits with data are obtained without modifying any of the potential parameters. The extracted deformation parameters and reaction and total cross sections are also considered.

• Article: Research with fast radioactive isotope beams at RIKEN

  ABSTRACT: The RIKEN RI Beam Factory (RIBF) provides intense radioactive isotope (RI) beams with energies around 200 MeV/nucleon in a wide range of unstable nuclei. Part of the facility started routine operation in 1987 and, in 1990, RI beams from this part became available, with energies of a few tens of MeV/nucleon and the world's highest intensities at the time for many light exotic nuclei. To exploit the research opportunities available with such fast RI beams, various experimental devices have been constructed and several new methods have been developed. A number of modern aspects of nuclear structure, such as the neutron halo and the disappearance/appearance of magic numbers, have been investigated. Several attempts to approach astrophysical nuclear processes involving short-lived nuclei have been made. The present RIBF facility was completed in 2006. It far exceeds other existing facilities in the world in its RI beam production capability. A variety of research programs have been started, and several groundbreaking results have already been obtained.

• Article: Vibrational spectra and elastic piezoelectric and polarization properties of the alpha-SrB4O7 crystal

  ABSTRACT: The crystal lattice vibrational frequencies in the center of the Brillouin zone have been determined with the Raman spectroscopy method. The lattice vibrational frequencies, the phonon density of states, elastic and piezoelectric moduli, Born dynamic charges, and high-frequency dielectric constant have been calculated using the density functional method. All calculated quantities have been compared to the experimental data. A model of a nonpolar paraelectric phase for this compound, as well as a mechanism of the formation of domain in it, has been proposed. The polarization in the experimentally observed polar phase has been calculated.

• Article: Development of the new approach to the diffusion-limited reaction rate theory

  [show abstract] [hide abstract]
  ABSTRACT: A new approach to the diffusion-limited reaction rate theory, recently proposed by the author, is further developed on the base of a similar approach to consideration of Brownian coagulation. The traditional diffusion approach to calculation of the reaction rate is critically analyzed. In particular, it is shown that the traditional approach is applicable only to the special case of reactions with a large reaction radius, rA<<RAB<<rB (where rA, rB are the mean inter-particle distances), and becomes inappropriate to calculation of the reaction rate in the case of a relatively small reaction radius, RAB<<rA, rB. In the latter, most important for chemical reactions case particles collisions occur mainly in the kinetic regime (rather than in the diffusion one) characterized by homogeneous (at random) spatial distribution of particles on the length scale of the mean inter-particle distance. The calculated reaction rate for a small reaction radius in 3-d formally (and casually) coincides with the expression derived in the traditional approach for reactions with a large reaction radius, however, notably deviates at large times from the traditional result in the plane (2-d) geometry. In application to reactions on discrete lattice sites, new relationships for the reaction rate constants are derived either for 3-d or for 2-d lattices.

• Article: Narrow �Band N �Resonance Formed in Thin Rubidium Atomic Layers

  ABSTRACT: The narrow�band N �resonance formed in a Λ system of D1� line rubidium atoms is studied in the presence of a buffer gas (neon) and the radiations of two continuous narrow�band diode lasers. Special�pur� pose cells are used to investigate the dependence of the process on vapor column thickness L in millimeter, micrometer, and nanometer ranges. A comparison of the dependences of the N�resonance and the electro� magnetically induced transparency (EIT) resonance on L demonstrates that the minimum (record) thickness at which the N�resonance can be detected is L = 50 μm and that a high�contrast EIT resonance can easily be formed even at L ≈ 800 nm. The N�resonance in a magnetic field for 85 Rb atoms is shown to split into five or six components depending on the magnetic field and laser radiation directions. The results obtained indicate that levels Fg = 2, 3 are initial and final in the N �resonance formation. The dependence of the N �resonance on the angle between the laser beams is analyzed, and practical applications are noted.

• Article: Effect of impurities on the heat capacity of quasi-one-dimensional conductors

  [show abstract] [hide abstract]
  ABSTRACT: The low-temperature heat capacity of a quasi-one-dimensional conductor in the Luttinger liquid state is studied for conductors with a charge density wave and without it. It is shown that pinning of the Luttinger liquid leads to localization of spins and a strong effect of the magnetic field on the thermodynamics of samples resembling the effect observed in recent experiments. We believe that this indicates the possibility of the formation of a Luttinger liquid in quasi-one-dimensional crystals.
