Angular correlation and differential cross sections in e--H(1 (2)S-3 (2)P) excitation.

Abstract

Differential cross sections and angular correlation parameters are calculated for electron-impact excitation of the 3 $^{2}$P state in hydrogen from the ground ${1}^{2}$S state using a distorted-wave approximation. The calculations are compared with the recently reported experimental and close-coupling theoretical results of J. F. Williams, A. T. Stelbovics, and I. Bray [J. Phys. B 26, 4599 (1993)]. Present results show reasonably good agreement with both of their theoretical and experimental results.
