Coulomb Wave Amplitudes forL=0Stripping Reactions

Abstract

We obtain a simple analytic expression for an $L=0\mathrm{}$ stripping amplitude, using a Coulomb wave for the relative motion of the incident particles, and a plane wave for the relative motion of the products. If the initial and final-bound states may be considered asymptotic, having wave functions of the form $\frac{e^{-\lambda r}}{r}$, the cross sections predicted have an angular dependence identical to that predicted by a plane-wave calculation. The use of a Coulomb wave for the incident relative motion modifies only the absolute magnitude of the cross section.
