Investigation of the optical potentials for the 40Ca(α,t)41Sc reaction at 40 MeV

The 40 Ca( α , t ) 41 Sc reaction has been studied at a 40 MeV incident energy. The angular distributions of the eight states of the reaction are analyzed using the full finite-range (FFR) distorted-wave Born approximation (DWBA) for both the bound and the unbound states of the 41 Sc nucleus using t...

Description
Summary:The 40 Ca( α , t ) 41 Sc reaction has been studied at a 40 MeV incident energy. The angular distributions of the eight states of the reaction are analyzed using the full finite-range (FFR) distorted-wave Born approximation (DWBA) for both the bound and the unbound states of the 41 Sc nucleus using the normal optical, Michel and molecular potentials. The spectroscopic factors that have been extracted for the three optical potentials are compared with the previous local zero-range (LZR) and local finite-range (LFR) calculations of the 40 Ca( α , t ) 41 Sc reaction for the normal optical potential. The χ 2 values of all the potentials for different l transfers are calculated to estimate the quality of fits. The present analysis shows that the Michel and the molecular potentials fit the data more satisfactorily than the normal optical potential.
