摘要：

The broadband radiation emitted from a Na Z pinch is used to photoionize Ne to the He-like ground state and radiation from the Na 1s2-1 s2-1 s 2p P-1(1) transition is used to resonantly photoexcite the Ne 1s2-1s4p P-1(1) transition. Time-resolved and time-integrated spectral measurements of the Ne K-shell emission demonstrate the first population inversion driven by a Z pinch. This is the first experiment in any medium to demonstrate a soft-x-ray inversion pumped solely by resonant photoexcitation.
