Gamma Rays from Neutron Inelastic Scattering inB10,F19, andFe56

The cross section for excitation of the 0.72-Mev gamma ray in the B/sup 10/(n.n' gamma )B/sup 10/ reaction was measured from threshold to 5.2 Mev. Resonances were observed at 1.93, at 2.6 Mev. The angular distributions of the 0.110-Mev and 0.197-Mev gamma rays in the F/sup 19/(n,n' gamma )F/sup 19/ reaction and the 0.847-Mev gamma ray in the Fe/sup 56/(n.n' gamma )Fe/sup 56/ reaction were also measured ai 2.56 Mev. The first of these was isotropic. the last two showed anisotropies but were symmetrical about 90 deg . The angular distribution of the Fe/sup 56/ gamma ray agrees well in both shape and absolute magnitude with calculaiions based on the statistical model. (auth)
