Delayed x-ray emission has been observed in highly ionized oxygen for both the 1s-n p H-like (Lyman) and the 1s2-1snp (S1-P1) He-like sequence. Within less than 0.5 nsec after formation, the shapes of the decay curves for all the measured transitions were found to be similar, each following a power-law time dependence. This nonexponential shape for the decay curves is attributed to cascade effects from states near the ionization limit.
