Energy Levels in Light Nuclei

Abstract

Targets of beryllium, Nylon, lead fluoride, sulfur, and lead sulfide were bombarded with 8-Mev protons from the University of Pittsburgh cyclotron. Energy levels were observed in ${\mathrm{Be}}^9$, ${\mathrm{C}}^{12}$, ${\mathrm{N}}^{14}$, ${\mathrm{O}}^{16}$, ${\mathrm{F}}^{19}$, and ${\mathrm{S}}^{32}$ by inelastic scattering at 150° from thin targets. Single levels were assigned in ${\mathrm{Be}}^9$ and ${\mathrm{C}}^{12}$; two levels were assigned in ${\mathrm{N}}^{14}$; nine levels were assigned in ${\mathrm{F}}^{19}$; and seven levels were assigned in ${\mathrm{S}}^{32}$.
