Nuclear Reactions of V with 300-GeV Protons and Co with 11.5-, 200-, and 300-GeV Protons

Cross sections of a large variety of spallation products from V and Co do not change appreciably as the beam energy increases from 11.5 to 300 GeV. The mean ratio $\frac{{\sigma }_{300}}{{\sigma }_{29}}$ for V is 0.96±0.04; for Co, $\frac{{\sigma }_{200}}{{\sigma }_{11.5}}=0.95\mathrm{}\pm 0.06$ and $\frac{{\sigma }_{300}}{{\sigma }_{11.5}}=1.02\mathrm{}\pm 0.09$. It was assumed that the monitor cross section is constant above 10 GeV.
