Gamma Radiation from Proton Bombardment ofLi7

The capture $\gamma$ rays from the reaction ${\mathrm{Li}}^7(p, \gamma )$ have been investigated by measuring excitation functions and angular distributions. In addition to the well-known resonance at 441 kev, the excitation curve exhibits resonance at 1030 kev in proton bombarding energy corresponding to an excited state at 18.14 Mev in ${\mathrm{Be}}^8$. Near this resonance the $\gamma$ rays have a nonisotropic angular distribution with fore-and-aft asymmetry. The yield integrated over this resonance corresponds to a radiation width given by $\omega {\Gamma }_{\gamma }=2\mathrm{}$ ev.
