γRays from Resonance Neutron Capture inU235

High-energy capture $\gamma$ rays emitted from resonance neutron capture in ${\mathrm{U}}^{235}$ have been observed. In addition to known levels in ${\mathrm{U}}^{236}$ at 149 and 688 keV, six previously unobserved levels are populated, four of which appear to be members of the $\beta$ and $\gamma$ vibrational bands. Direct transitions from the capture state to spin-2 levels indicate that the 2.040- and 6.39-e V resonances have spin 3. The neutron separation energy of ${\mathrm{U}}^{236}$ is 6545±2 keV.
