ReactionsCu63(p, n)Zn63andCu63(p, 2n)Zn62from 1.5 to 11.5 GeV

Abstract

Total cross sections for the $^{63}\mathrm{Cu}(p, n)^{63}\mathrm{Zn}$ and $^{63}\mathrm{Cu}(p, 2n)^{62}\mathrm{Zn}$ reactions at 1.5, 2.0, 3.0, 4.5, 6.0, 9.0, and 11.5 GeV have been determined. These results are used to normalize previous differential-recoil angular-distribution data for the ($p, 2n$) reaction at 1.0 GeV. A comparison with similar data for the $^{65}\mathrm{Cu}(p, pn)^{64}\mathrm{Cu}$ reaction indicates that, for energy transfers sufficient to evaporate only one nucleon, the inelastic ($p$, ${p}^{\ensuremath{'}}$) reaction is approximately 100 times more probable than the ($p$, $n$) interaction at this energy.
