Scattering s-wave electrons off atomic hydrogen.

The Kohn variational method of calculating scattering phase shifts has been examined previously, and calculations of the phase shifts of S-wave electrons on atomic hydrogen done, by Schwartz. This paper presents the results of using a trial function somewhat simpler than Schwartz's and compares the two sets of results. In addition this paper presents and compares the results of two different normalizations of the variational principle and gives a somewhat more detailed development of the variational principle used than in most previous papers.http://www.archive.org/details/scatteringswavee00elsbFirst Lieutenant, United States Air ForceApproved for public release; distribution is unlimited
