Within the usual assumptions associated with sudden-approximation analyses of photoelectron spectm. it is shown that unrelaxed subshell cross sections calculated on the basis of unit overlap between initial-and final-state-passive electrons implicitly include the effects of both one-electron and mul

โฆ Synopsis
The factorization expression for degeneracy averaged differential cross sections reported by Goldflam et al. and also by Khare is tested using accurate close coupling input for He-CO. The results illustrate the accuracy of factorization expressions in describing detailed scattering phenomena.

The assumptions of the infinite-order sudden (10s) approximation are examined by testing them on an accurately calculated scattering matrix. It was found that the accurate S matrix was not even roughly diagonal in the IOS representation. If, however, the elastic phase shift is removed from the scatt
