Abstract
The theoretical calculation of the cross section for formation of 56,57co in (p, n) reaction from 56,57Fe target have been studied from reaction threshold to 30 MeV using TALyS-1.4 nuclear model reaction code whereby we have studied major nuclear reaction mechanisms, including direct, preequilibrium and compound nuclear reactions. These calculations were carried out by adjusting the effective imaginary potential, level density and shell damping parameters. It is observed that an excellent agreement between the theoretical calculated and experimental data is obtained with minimal effort on parameter fitting. we have also observed that there is significant contribution of pre-equilibrium emission in (p, n) reaction cross-section of 56Fe and 57Fe. The systematic increase in (p, n) cross-sections with increasing neutron number in reactions induced by protons on 56Fe and 57Fe is explained in terms of compound and pre-equilibrium mode.

Analysis and characterization of neutron scattering of a Linear Accelerator (LINAC) on medical applications.
In several theoretical and experimental studies, the topic of the undesirable generation of photoneutrons in rooms where a linear accelerator (LINAC) operates has been discussed. When energies above 10 MeV are used to pr...
Study of H2/N2Mixture Plasma Treatment on the AISI 1045
In the present work, we analyzed the effect of the plasma treatment of 80% H2/20% N2 mixture plasma over the AISI 1045 steel. To produce the plasma, an AC discharge of 0.1 A at 350 V was produced at a total pressure of 3...
Radio-Optically- and Thermally Stimulated Luminescence of Zn(BO2)2:Tb3+ exposed to Ionizing Radiation
The optical absorption of zinc tetraborate at different concentrations of the terbium impurity (0, 0.5, 1, 2, 4, 8 mol%) was analyzed. The radioluminescence (RL) emission spectra was obtained after beta irradiation of a...
Formation of Medium-Heavy Elements in Rapid Neutron Capture Process
We predict the neutron drip-line and simulate the r—process path for Cu — Sn, based on the calculation of binding energy in the frame-work of relativistic and non-relativistic mean field formalisms. We also compare the q...
