Study of Angular Momentum Transfer in Electron-Impact 2s→2p Excitation for Lithium Isoelectronic Sequence
TL;DR: In this article, the angular momentum transfer (AMT) as a function of scattering angle is investigated for the lithium isoelectronic sequence with nuclear charge Z = 3-6, and distorted-wave (DW) and close-coupling (CC) calculations are applied to investigate the AMT.
