Radiative and autoionization rates of the metastable 24 P 0 J states in lithiumlike neon

Abstract

Atoms.Molecules zo,,0o.r,, and ClustersThe delayed X-ray and electron emission from metastabte states in fast, foil excited neon ions has been investigated. High resolution X-ray and electron spectroscopy at calibrated relative detection efficiencies was applied to determine fluorescence yields for the radiative decay of the (ls2s2p)4Ps °, J = 1/2, 3/2, 5/2 states in NeVIII. Using measured total lifetimes corrected for cascading effects the forbidden radiative and autoionization rates were determined.
