The recoil electron spectrum of the gamma-rays from {\mathrm{As}}^{76}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\ifmmode\pm\else\textpm\fi{}0.02 and 1.94\ifmmode\pm\else\textpm\fi{}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 {\mathrm{Se}}^{76}residual nucleus. No...
