Resonance Energies and Widths from the Poles of the Multichannel T matrix

Abstract

A multichannel iteration technique was developed to obtain accurate results for phase shifts from a 'smooth' Schwinger K matrix. Applications were made to e + He+ phase shifts in one, two, and three channel approximations. A second project was started to study excited states of helium using dimensional analysis. A moment method is being used to solve the two-electron Schrodinger equation generalized to an arbitrary number of dimensions. (kr)
