POLARIZATION IN THE ELASTIC SCATTERING OF 2-3 Mev NEUTRONS BY DEUTERONS
Large polarization effects have been observed in the elastic scattering of polarized neutrons from the D--D reaction by deuterons. The polarization for 90 d center of mass scattering is 0.58 plus or minus 0.05 at 2.26 Mev and 0.86 plus or minus 0.19 at 3.1 Mev and was measured by studying the asymmetry in the distribution of recoil deuterons in deuterium filled proportional counters. (auth) l4312 The differential cross sections for the inelastic scattering of protons at intermediate energies are calculated in an analytical way on the basis of the statistical independent particle model with a diffuse nuclear surface, assuming that nnain contribution to the cross section comes from the direct interactions of incident protons with the target nucleons penetrating out beyond some critical radius in the diffuse rim of the nucleus, and taking the Pauli principle exactly into consideration. The contribution of the compound nucleus formation process to the cross section was also estimated. The application to the inelastic scattering of 31 Mev protons by Sn leads to values of the cross sections in good agreement with the experiment. (auth)
