Title: Unitarized First-order Many-body Approximation For The Electron Impact Excitation Of Triplet States Of Helium
Author: Silva Jr. O.S.
Da Paixao F.J.
Abstract: We use unitarized first-order many-body theory (UFMB) to obtain differential cross sections for the electron impact excitation of the 2 3S and 2 3P states of helium in the intermediate energy range. Our results are in much better agreement with experiment than previous calculations using the weak-coupling approach. © 1994 1OP Publishing Ltd.
