Abstract
The recoil electron spectrum of the gamma-rays from has been examined in a magnetic spectrograph. The spectrum was found to be composed of two electron groups corresponding to quantum energies of 0.83±0.02 and 1.94±0.04 Mev, the intensity ratio being 3.8:1. These results suggest excitation levels at 0.8 Mev and 2.8 Mev in the residual nucleus. No contributions to the spectrum of gamma-rays of energy greater than 1.94 Mev were observable.
