Plasma screening and configuration interaction effects induced large enhancement on L-shell photoionization cross sections and opacity
Fuyang Zhou, Shengbo Niu, Simei Lu +5
An opacity model that incorporates improved treatments of both plasma screening and configuration interaction (CI) effects is proposed, and a 25-30% enhancement on the iron L-shell…
