Delayed-Neutron Spectra Following Decay ofAs85andSb135

The delayed-neutron spectra following decay of 2.05-sec ${}_{}{}^{85}{}_{}{}^{}\mathrm{As}$ and 1.7-sec ${}_{}{}^{135}{}_{}{}^{}\mathrm{Sb}$ are found to consist of a small number of discrete lines and the fluctuations in the experimental spectra differ significantly from those calculated with a statistical model. The data indicate that the $\beta$-strength function for these decays contains narrow resonances in the energy range 5-8 MeV.
