Analysis of inelastic scattering of He-3 on C-14 at 37.9 MeV .1. Collective model

The differential cross sections of elastic and inelastic scattering of He-3 ions on the C-14 nucleus have been measured at an energy of 37.9 MeV. By fitting the shape of the measured angular distribution of the elastic scattering the parameters of the optical model have been found. These parameters have been used for the standard DWBA calculations of angular distributions corresponding to excitations of the C-14 levels 6.73(3(-)), 7.01(2(+)) and 8.32(2(+)) MeV and for coupled channels calculations of the level 8.32(2(+)) MeV. The vibration parameters beta(L) of the C-14 nucleus have been deduced.
