Abstract

Activation measurements of the ${}^{7}{Li}$ ( $p$ , $n$ ) ${}^{7}{Be}$ (g.s.+ 0.43 MeV) total reaction cross section have been made at 12 proton energies between 60-200 MeV, with typical uncertainties of 8-14%. The measured total reaction cross section $σ (E)$ is $\dot{o}$ bserved to vary inversely with incident proton energy, and to agree very well, when extrapolated to lower energies, with previously published results in the energy range 25-45 MeV. A theoretical interpretation of this energy dependence is presented.
