Abstract
Population dynamics of atomic inner-shell vacancy states are analyzed for t he possibility of inversion in relation to keV x-ray laser schemes. Transit ions between pairs of inner-shell vacancy states are considered in which th e states are pumped via electron-impact inner-shell ionization by a femtose cond high-energy electron pulse. For appropriate atomic systems, transient inversion is predicted due to rapid lower state depopulation via Coster-Kro nig decay. [S1050-2947(99)50206-0].
