抄録

Three-photon double ionization of an Ar atom has been investigated by photoelectron spectroscopy using an extreme ultraviolet free-electron laser. When the photon energy of the laser has been tuned to the resonances of the intermediate Ar⁺ ion, photoelectron peaks due to the resonant two-photon single ionization of the Ar⁺ ion have been observed. And it has been revealed that the appearance of the peaks is controlled by the mixing ratios of 3p⁴ core-configurations of the multi-configuration states. Furthermore, it has been shown that the laser intensity dependence of the Ar²⁺ ion production rate due to the resonant two-photon single ionization strongly deviates from that expected by perturbation theory.
