This thesis describes optical-model analyses of the elastic scattering of 3He particles by 12C at 18,0 MeV. The analyses were performed on a H-1800 computer at the Systems and Research Division of Honeywell, Inc., Minneapolis, Minnesota, and on an IBM-360/40 at the Ball State University Computing Center. The angular distributions of the elastic scattering of 18.0-MeV 3He particles from 12C were analyzed in terms of a four-parameter optical potential having either a surface-absorption or volume-absorption term. Four sets of parameters of the surface-absorption type were found which best described the experimental data, The quality of fits showed little improvement when six-parameter potentials were used or when a spin-orbit term was included. Although only forward angles were included in the searches, good agreement resulted between the backward-angle experimental data and optical-model predictions. One of the four sets of parameters was chosen which provided the best overall descriptions to the elastic scattering of 3He from 12C at 13.9, 16,0, and 17.0 MeV. These results were quite inferior to the results obtained for the 18.0-MeV data.
