Investigation of the proton induced reactions on tin at low energies.

Radioactive isotopes of antimony could be produced from proton induced reactions on tin isotopes. At low energy, (p,n) reactions are the only open channels. Measurements are performed for proton reactions with (124)Sn in the energy range between 9.0 and 18.0MeV. Evaluations of the remaining possible reactions are performed and compared with each other. The cross sections are calculated theoretically by the EMPIRE-II code for (124)Sn(p,n)(124)Sb reaction. However, the calculations failed to agree with the experimental results. A recommended evaluation is given and the thick target yields are calculated from the evaluated approximations.

Experimental investigation and nuclear model calculations on proton-induced reactions on highly enriched 114Cd at low energies.

The excitation functions of both Cd(p,n)(114m)In114 and Cd(p,2n)(113m)In114 reactions were evaluated experimentally by the stacked-foil technique on highly enriched (114)Cd isotope. Two stacks were irradiated by proton beam with energies 14.7 and 18MeV on the MGC-20 cyclotron at Nuclear Research Center, AEA, Egypt. The present results support the previous measurements. The theoretical interpretations of the measured excitation functions were done by EMPIRE-II (v2.18 Mondovi) code. Compatibility with predictions of hybrid Monte Carlo simulation (HMS) pre-equilibrium mechanism was obtained.
