A DWBA study of the 48Ca( $\alpha$ ,t)49Sc reaction using shallow (molecular), deep non-monotonic, Michel and normal optical potentials

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.
