The Distribution in Angle of Alpha-Particles from Lithium Bombarded with Protons

Abstract

The distribution in angle of alpha-particles from ${\mathrm{Li}}^{7}$+${\mathrm{H}}^{1}$ is found to be of the form $1+\mathrm{A}{cos}^{2}\ensuremath{\theta}$. The variation of $A$ with bombarding energy is characterized by a rapid increase in the range 250 to 325 kev presumably indicating resonance to a broad excited level of ${\mathrm{Be}}^{8}$.
