Abstract

New high-resolution experimental results on Ne $1 s$ near-threshold photoionization with subsequent decay into a $2 p^{4} ({}^{1}D_{2}) n^{'} p$ or $2 p^{4} ({}^{1}D_{2}) ε^{'} p$ state are presented. The population of Rydberg states up to $n^{'} = 12$ is determined as a function of excess energy. These data allow one to track in detail the transition from resonant Auger decay going along with shake-up of the spectator electron to shake-down and photoionization with recapture of the photoelectron. Results are in good agreement with a time-dependent quantum mechanical theory of Auger decay in the presence of a slow photoelectron.
