Abstract

The angular correlation $f$ of the neutrons to the first excited state in ${Be}^{7}$ and the associated 430-kev gamma rays has been measured. Energy selection of the neutrons was made possible by a time-of-flight spectrometer. The angular correlations were predominantly isotropic at bombarding energies below 600 kev, while above this energy the correlations showed a strong peaking in the beam direction. Analysis using stripping theory shows that the 430-kev state is very probably a $J = \frac{1}{2} -$ state. The excitation function corrected for Coulomb penetration shows a resonance corresponding to an excited state in ${Be}^{8}$ at 22.6 Mev.
