Excitation functions and cross section ratios for the formation of the isomeric pairs 102m,g;101m,g;99m,gRh in the natPd(p,2pxn) reactions

Excitation functions of the natPd(p,2pxn)102m,g;101m,g;99m,gRh reactions and the cross section ratios for the isomeric pairs 102m,gRh, 101m,gRh and 99m,gRh have been measured up to 42.61 MeV. The experiments were carried out using a stacked-foil activation technique. The proton beam intensity was determined based on the natCu(p,xn)62Zn and natCu(p,xn)65Zn monitoring reactions. The activities of the irradiated palladium and cooper monitor foils were measured using a HPGe γ-ray detector. The present experimental cross sections are compared with reference data and with the theoretical predictions from TENDL-2015 libraries. The cross sections for the nuclear reactions natPd(p,2pxn)102m,gRh were measured in the energy range of 20-40 MeV and the cross section ratios for all three isomeric pairs 102m,gRh, 101m,gRh and 99m,gRh produced in the natPd(p,2pxn) reactions are the first measurements.
