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

抄録

The nucleus ¹²C was bombarded by 82.1–MeV ³He particles to study elastic and inelastic scattering and the (³He, 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 ¹²C, and for the (³He, α) reaction to levels at 0.0, 2.0, 4.3(4.7) and 6.4 MeV in ¹¹C. The optical potential parameters were searched for to fit the ³He elastic scattering angular distribution. The deformation parameters β₂ and β₃ for ¹²C were determined from DWBA analysis. The angular distributions of α particles were compared with DWBA calculations and calculations including the two-step process via inelastic channel.
