In order to clarify an interaction between xenon (Xe) clusters and a soft xray laser (wavelength: 13.9 nm, pulse width: ~7 ps, intensity: 2×1010 W/cm2), we measured the energy distribution of photo- and Auger electrons as well as the ion mass spectrum. Since the photon energy of the soft x-ray laser (89.2 eV) is sufficiently high to photoionize Xe 4d inner electrons, inner-shell ionization rather than valence-shell ionization is the dominant ionization process, resulting in the Auger decay. It was found that prominent photo- and Auger electron peaks were not observed, while the continuum energy spectra dominated line peaks. Moreover, the energy distribution obtained implies the production of low temperature plasma.
