Abstract

Ionization yields versus laser intensity have been measured for He-like In+-Ions, metastable Kr* and ground-state Kr, using a 50-fs Ti: Sapphire laser at λ = 800 nm. A clear signature of non-sequential ionization has been found for In+, but the result is qualitatively different from previous helium data. A dramatic influence of ionization rate due to target excitation was found in metastable Kr*. The multiple ionization yields in Kr (up to Kr4+) and in Indium are excellently reproduced by a novel collective tunnel ionization formula with zero free parameters, which has been developed in our laboratory.
