Abstract
Nuclear resonant scattering of bremsstrahlung by the 3.00-MeV level of has been observed. From comparison with resonant scattering by the 2.98-MeV level of , and with the branching taken from the literature as , widths meV and meV are obtained. These values are in some disagreement with inelastic electron scattering results. Comparison with Doppler-shift values tends to verify for the 3.00-MeV level and to rule out . Self-absorption measurements of the resonant scattering by the 2.21- and 2.98-MeV levels of give meV and meV, in agreement with previous results. Self-absorption measurements for the 3.13-MeV level of give meV.
