Abstract

Full finite-range (FFR) distorted wave Born approximation (DWBA) calculations have been performed using four types of optical potentials, namely shallow (molecular), deep non-monotonic, Michel and normal optical potentials to analyze the angular distributions of the 21 transitions in the bound states of the ⁴⁸Ca( $\alpha$ , t)⁴⁹Sc reaction at 36MeV incident energy. Spectroscopic factors extracted for the levels using all these potentials are compared with those obtained from previous zero range calculations of ⁴⁸Ca( $\alpha$ , t)⁴⁹Sc reaction using the normal optical potential. The normal optical and deep non-monotonic potentials fit the data satisfactorily but the shallow (molecular) and Michel potentials are not so adequate to reproduce the data for all the levels.
