A comment on the reaction 10B(t,p) 12B

Abstract

The 10B(t,p) ground state angular distribution has been quoted as one of the clearest indications of a two-step reaction mechanism. As, however, no DWBA calculations were performed, one might doubt, whether the unusual angular distribution was not due to coincidental peculiarities lost in the plane wave description. Our DWBA calculation indicates, that the basis for ruling out a one-step mechanism is weakened when distorted waves are introduced, but that there is still room left for components of various two-step mechanisms.
