Probabilities for transition processes crucial to Li lasers

Abstract
We present results of electron corrrelation calculations in the Briet-Pauli approximation for radiative allowed and forbidden transition probabilities of highly excited Li states, contained in recent schemes for short-wavelength lasers. This is the first quantitative prediction for the phenomenon of relativistic radiative autoionization (RRA). RA has already been singled out as a fundamental deexcitation mechanism which might lead to efficient lasing systems.
