Improved effective momentum approximation for quasielastic scattering off highly charged nuclei
Institute for Physics, University of Basel - 4056 Basel, Switzerland
Accepted: 14 June 2004
We address the problem of including Coulomb distortion effects in inclusive quasielastic reactions using an improved version of the effective momentum approximation. Arguments are given that a simple modification of the effective momentum approximation, which is no longer applicable in its original form in the case of highly charged nuclei, leads to very good results. A comparison of the improved effective momentum method with exact calculations is given. A critical remark concerns recent experiments with inclusive quasielastic positron scattering.
