The (3He, 3He), (3He, 3He') and (3He, α) Reactions on 12C at 82.1 MeV

The nucleus 12 C was bombarded by 82.1–MeV 3 He particles to study elastic and inelastic scattering and the ( 3 He, α) reaction. Angular distributions were measured for the elastic scattering, for the inelastic scattering to levels at 4.4, 7.6 and 9.6 MeV in 12 C, and for the ( 3 He, α) reaction to levels at 0.0, 2.0, 4.3(4.7) and 6.4 MeV in 11 C. The optical potential parameters were searched for to fit the 3 He elastic scattering angular distribution. The deformation parameters β 2 and β 3 for 12 C were determined from DWBA analysis. The angular distributions of a particles were compared with DWBA calculations and calculations including the two-step process via inelastic channel.
