Momentum spectroscopy of fragment ions emitted from Xe clusters irradiated by EUV-FEL at SPring-8

We have studied multiple ionization of Xe clusters by 61-nm 1011−1012 W/cm2extreme-ultraviolet light pulses at the free-electron laser facility, SPring-8 Compact SASE Source test accelerator, in Japan. Kinetic energy distributions of Xe+, Xe+2, Xe+3, and Xe+4 ions emitted from Xe clusters were measured.
