Title: Electron Impact Excitation Of The Metastable He(2 3s)
Author: Franca A.
Da Paixao F.J.
Abstract: The first-order many-body theory is applied to study the inelastic collision of unpolarized electrons with helium in the 2 3S excited state. The authors calculate differential cross sections (DCS) and integral cross sections (ICS) for 2 3S → 2 3P, 3 3S, 3 3P transitions and the alignment and orientation parameters for the 2 3S to 2 3P, 3 3P transitions. The calculated DCS for the transition 2 3S→ 2 3P is in good agreement with published theoretical and experimental results. The general behaviour of the alignment and orientation parameters for He 2 3S→ 2 3P transition is compared with that of the Na 3 2S → 3 2P transition. © 1994 IOP Publishing Ltd.
