ABSTRACT The 27Al(d,x)22,24Na reactions are frequently used to monitor deuteron beams above 20 MeV. To extend possible monitoring energy region toward lower energies, new monitor reactions are proposed and experimental cross-sections are measured for the processes 27Al(d,x)22,24Na, natTi(d,x)48V, natFe(d,x)56Co, natNi(d,x)61Cu and natCu(d,x)65Zn. The excitation functions were studied using the activation method on stacks of thin metallic foil targets with natural isotopic composition. The data sets of the six processes were cross-checked with each other to provide reliable numerical cross-sections. Detailed literature compilation and critical comparison were made on the available data sets for the studied reactions. Predictions of model calculations were compared with the new experimental data. After establishing selection criteria, consistent data sets were chosen for each of the processes, which were then fitted with a spline or Padé method to provide recommended cross-sections.

    ABSTRACT: In order to complement the scarce experimental data for activation of natSi in deuteron irradiations, we performed measurements with incident particle energy up to 50 MeV. The activation products 7Be, 22,24Na and 28Mg were assessed with HPGe spectroscopy and excitation functions for the corresponding natSi (d,x) reactions are presented. A comparison with the only previous experimental study and with results obtained from the codes EMPIRE-D, ALICE-D and the online libraries EAF2007 and TENDL2011 is made. Thick target yields and total induced activity for long exposures of Si containing structural elements or measuring devices around a high power deuteron accelerator were calculated.

    ABSTRACT: The reaction cross sections for different residual nuclides produced in the charged particle (p, d, 3He and α) induced reactions were calculated and compared with the existing experimental data which are important for beam monitoring and medical diagnostic applications. A detailed literature compilation and comparison were made on the available data sets for the above reactions. These calculations were carried out using the statistical model code TALYS up to 100 MeV, which contains Kalbach’s latest systematic for the emission of complex particles and complex particle-induced reactions. All optical model calculations were performed by ECIS-03, which is built into TALYS. The level density, optical model potential parameters were adjusted to get the better description of experimental data. Various pre-equilibrium models were used in the present calculations with default parameters.

    ABSTRACT: Activation cross-sections of the natFe(d,x)55,56,57,58g+mCo, 52g,54,56Mn, 51Cr, 59Fe reactions were measured from their respective thresholds to 24 MeV via a stacked foil activation technique combined with HPGe γ-ray spectrometry. An overall good agreement is found with some of the earlier measurements, whereas partial agreements are obtained with the theoretical data extracted from the TENDL-2011 library. The present measurement reports four cross-sections of 58g+mCo, 56Mn and 59Fe radionuclides in the energy range of 20-24 MeV for the first time. Physical thick target yields deduced from the measured cross-sections are compared with the directly measured yields available in the literature. The measured 58Fe(d,p)59Fe cross section is underestimated by the original TENDL-2011 library while overestimated by the TENDL-2011 library renormalized by Ignatyuk for the FENDL-3 library.
