Inelastic Scattering of 31-Mev Protons from Beryllium

The range spectrum of charged particles resulting from the bombardment of a thin beryllium foil by 31.3-Mev protons has been measured at several angles. In addition to previously reported energy levels in ${\mathrm{Be}}^9$ at 2.4, 6.8, and 11.3 Mev, evidence for new levels at 5.0, 7.9, 19.9, and 21.7 Mev was obtained. The angular distribution of each of the proton groups was interpreted in the light of the Austern-Butler-McManus peripheral scattering theory.
