Abstract

Based on the results of recent studies of microwave ionization of Rydberg states, estimates are obtained for the stability of excited states of highly charged ions under irradiation from a powerful excimer laser. The short lifetimes and associated line broadening suggest caution in the design of x-ray lasers using selective multiphoton excitation as a pumping mechanism.
