Convergent J-matrix Calculation of the Differential Cross-Sections for Electron-Helium Scattering.
Abstract
Despite the fact that J-matrix method was proposed over 20 years ago by Heller and Yamani(Heller E.J. and Yamani H.A. Phys. Rev A 9) 1201 (1974), numerically converged practical applications have only recently been reported by Konovalov and McCarthy(Konovalov D.A. and McCarthy I.E. J. Phys. B 27) L407-L412 and L741-L747 (1994). Here we report a detailed investigation of the J-matrix method for electron-helium scattering. Particular attention will be paid to the description of the initial target states and their influence on the final result. J-matrix results will be compared with other recent theoretical results and experimental data.
