Production cross-sections of residual radionuclides from proton-induced reactions on ~(nat)Ag up to 40 MeV

摘要

We measured the cross-sections of the ~(104g,105,106m)Ag and ~(104,107)Cd radionuclides produced by proton-induced reactions on natural silver by using a stacked-foil activation technique in the energy range from a threshold energy to 40 MeV at a MC50 cyclotron. The results showed generally good agreement with available data as well as the theoretical data. The integral yields for thick targets were also deduced using the measured cross-sections and the stopping power of ~(nat)Ag over the energy range from a threshold energy to 40 MeV, taking into account that the total energy is absorbed in the targets. The production cross-sections for the ~(104g)Ag and the ~(104)Cd radionuclides from natural silver were measured for the first time.
