Abstract
A distorted-wave Born-approximation (DWBA) formalism is developed to describe the “elastic” and “inelastic” breakup of the projectile in the heavy-ion-induced reasctions. Using a “local momentum approximation” and the surface localization property of these reactions expressions for the DWBA transition amplitude are derived. One of the attractive features of the present formulation is the fact that the radial integrals involved in it are the same as those contained in the transition amplitude evaluated with a zero range approximation. The validity of the approximations used in these derivations has been tested and it is shown that these approximations are well fulfilled.
