- Abstract
- The angular distributions of the elastic scattering of a particles by 28 Si have been measured at an incident energy of 120 MeV throughout the angular range of theta(c.m.) = 9.17 degrees to 54.27 degrees. Elastic cross sections have been analyzed in terms of an optical model by using a six-parameter volume-type Woods-Saxon potential. Optical potential parameters have been obtained by using the X 2 minimization method to compare calculations to experiments. We have verified various possibilities of potential ambiguities by using a reduced-parameter fit and a systematic grid search. Consequently, we have obtained three different optical potential parameter sets for the Si-28 + alpha reaction channel.
