Measurement of cross sections for the formation of 100gRh in natPd(p,x)100m,gRh reactions up to 42.61 MeV

Abstract

We measured the cross sections for the formation of the ground state nucleus 100gRh through natPd(p,x)100m,gRh reactions. The experiment was carried out using the stacked-foil activation technique in the energy range from threshold to 42.61 MeV. The cross section was determined on the basis of the measured activity of the corresponding residual nucleus using a high energy resolution HPGe γ-ray detector. The energy dependent flux of the proton beam was determined using the natCu(p,x)62Zn and natCu(p,x)65Zn monitoring reactions. In order to enhance the accuracy of the experimental results, the activity contributions from the decay of the 100mAg, 100gAg and 100Pd to 100gRh, which were also produced in the same palladium foil were corrected. The present experimental results are compared with the previously published data and with the theoretical predictions from the TENDL-2017 library.
