Nuclear Reactions of Silver with 300-GeV Protons

Cross sections of 27 radionuclides formed by the interaction of 300-GeV protons with silver were determined on the assumption that the cross section of the reaction ${}_{}{}^{27}{}_{}{}^{}\mathrm{Al}(p, 3pn)$ remains the same as at 10-30 GeV. The results are compared with the corresponding values obtained at 11.5 GeV. The average value of the ratio $\frac{{\sigma }_{300}}{{\sigma }_{11.5}}$ for all products ranging from ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$ to ${}_{}{}^{106m}{}_{}{}^{}\mathrm{Ag}$ is 0.91±0.07 and is independent of mass number.
