Study of Inner-Shell Ezcitation and Relazation Processes in Atomic and Ionic Neon by Means of Soft X-Ray Spectroscopy
By using soft X-ray spectroscopy, we investigate the inner-shell excitation and relaxation processes in atomic and ionic neon targets. Resonant X-ray emission spectroscopy was applied to neutral neon atom in the regions of the 1snp (n=3,4, ···,∈) excited states and 1s2p3pmp (m=3,4) doubly excited states to obtain the spectroscopic information on the 2pnp and 2p23pmp final electronic states, where square brackets indicate hole states. The energy levels of the 2p23pmp (m=3,4) electronic states were spectroscopically measured for the first time. As for the ionic neon target, on the other hand, the photoion yield spectroscopy was adopted to survey the 1s → np (n=2,3) resonant excitation and subsequent Auger decay processes for Ne+ target-ions. The observed Ne2+ photoion yield spectrum is successfully explained by the theoretical calculations based on the multiconfiguration Dirac-Fock method.
