title: Charge-state resolved above threshold ionization
abstract: Photoelectron energy resolved spectra recorded in coincidence with singly and doubly ionized atoms are reported for the interaction of xenon with 60 fs laser pulses at 800 nm and 1x10(14) W/cm(2). Double ionization contributions in the spectrum have been established. The appearance of a single ionization plateau in above threshold ionization is verified. A hotter electron distribution is found for the double ionization.
