Abstract
We observed the energy distribution of the photoelectrons generated fr om the highly charged ions in the tunneling regime by using a circular ly polarized Ti:Sapphire laser (745 nm, 100 fs). The peaks for each su ccessive charge state up to Ar3+, Kr4+, and Xe5+ were clearly resolved , and the peaks due to higher charge states were flattened in the high -energy region and deviated from those predicted by the quasistatic mo del. This deviation is explained by ponderomotive acceleration in the strong field gradient. In Xe, Xe8+ was generated at a peak intensity o f 2.0 x 10(16) W/cm(2).
