Abstract
We have observed more than fifty peaks between 400 keV and 4 MeV in photoneutron spectra of . Transitions occur to the ground state and first two excited states of from discrete absorption features, some of which are less than 100 keV wide even above 11 MeV. Three states, the most prominent of which is at 9.034 MeV, under lie a controversial electron-scattering resonance, supporting an rather than interpretation.
