The circular polarization of gamma rays following the capture of polarized neutrons was measured for some high-intensity transitions in S/sup 33/, Ti/sup 49/, Fe/sup 57/, Ni/sup 59/, Y/sup 90/ s, Al/sup 28/, Cu/sup 64/, and N/ sup 15/. The results are consistent with spin 1/2 for the 0.46 Mev level in N/ sup 59/ and spin 2 for the 0.277 Mev level in Cu/sup 64/. The following spins are confirmed: 3/2 for the 3.22 Mev level in S/sup 33/; 3/2 and 1/2 for the 1.38 and 1.72 Mev levels in Ti/sup 49/; 2 for the O.777 Mev level in Y/sup 90/. In N/ sup 15/, (25 plus or minus 18)% of captures belong to the ground state transition. In Al/sup 29/, information is obtained relating the mixture of spins in the capturing state and multipole mixtures and relative intensities of the components of the 7.72 Mev doublet. The results are compared with the prodictions of nuclear models and theories of thermal neutron capture. (auth)
