Abstract
The spectrum of rays following neutron capture at the 1167-eV resonance in has been measured at 90° and 135° to the incident beam. The partial widths for radiative decay have been determined and compared to the Weisskopf estimates. The and -ray strengths are found to be comparable, and a sizable ray in the resonance has been recorded. On the basis of the -ray measurements at two angles, and from what has been determined from other experiments, the spin and parity of the 1167-eV resonance are shown to be .
