The angular and energy distributions from the interaction of 14 Mev neutrons with /sup 6/Li and /sup 7/Li were determined from analysis of nuclear plate detectors placed at 10 deg intervals from 10 deg to 160 deg . The angular distributions of the elastically scattered neutrons are similar not only to those expected on the basis of diffraction scattering, but also to those obtained from an optical model analysis with parameters identical to those used for fitting medium-weight and heavy nuclei. The total elastic scattering cross section for 6/sup Li/ is 883 plus or minus 95 mb; for 7/sup Li/, 969 plus or minus 110 mb. The neutrons from inelastic collisions are much less peaked in the forward direction and exhibit a considerable isotropic component. The measured value for the total cross section for the emission of neutrons for /sup 6/Li is 1.44 plus or minus 0.16 b; for /sup 7/Li, 1.61 plus or minus 0.2 b. (auth)
