摘要：

We have measured the x-ray emission from high-rr spectator electrons following radiative stabilization in dielectronically excited highly charged barium, Baq+ (40 less than or equal to q less than or equal to 42) ions with open-shell configurations were produced with an electron beam ion trap tuned to an energy at which dielectronic capture into states with n=6-8 takes place. The highly excited spectator electron decays via radiative cascades, and the dominant signature of this process is an enhanced emission in regions of the barium spectra where transitions from higher ri to the n=3 level are located.
