Abstract

We use recapture of near-threshold photoelectrons by postcollision interaction with Auger electrons as an effective method for population of the high-Rydberg states of subvalence ionized Ne ions. The subsequent intermultiplet Auger transitions are detected by high-resolution electron spectrometry. The series of transitions $2 p^{4} ({}^{1}D) n p {}^{2}D, {}^{2}F \to 2 p^{4} {}^{3}P$ up to $n = 20$ are observed and identified with the help of multiconfiguration Dirac–Fock ab initio calculations.
