Abstract

Abstract 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.
