Influence of Breakup Channels on the Analysis of Deuteron Stripping Reactions

It is shown by explicit calculations that the adiabatic treatment of certain deuteron breakup channels predicts differential cross sections for ($d,p$) and ($p,d$) reactions, involving 20-MeV deuterons and a wide range of targets, similar to results obtained with the distorted-wave method but with large suppression of the contributions from low partial waves. An improved fit to angular distributions is obtained in many cases.
