Photoionization of He in the 3lnl' doubly-excited state energy region: angular distribution of the flourescence from the residual ion He + (2p) 2 P

Abstract

We present experimental observations of the photoexcitation of 3lnl′ doubly-excited states of helium decaying by autoionization into the (2p) 2P excited ion final-state channel. By determining the angular distribution of the fluorescence from the final Show more
