Times Cited Count：68 Percentile：87.93(Physics, Multidisciplinary)We report on detailed investigations of ionization dynamics of a Xe atom exposed to intense 800-nm pulses of 20-fs duration in the extensive intensity range from 10
to 10
W/cm
. Ion yields of Xe
to Xe
were observed as a function of laser intensity and compared with the results from a single active electron based Ammosov-Delone-Krainov model. Unexpected ionization probabilities for lower charge states and also no interplay between the inner- and outer-shells by screening are inferred. Suppression of nonsequential ionization towards higher intensity and few optical cycle regimes is also proved.

Times Cited Count：4 Percentile：33.69(Instruments & Instrumentation)Auger and Coster-Kronig electron spectra from highly excited states produced by low-energy highly charged ions with gas targets have been investigated both theoretically and experimentally. In this case, the highly excited states were formed by electron capture processes. We have studied collision processes of high-energy highly charged ions with a gas target using zero-degree electron spectroscopy at the tandem accelerator of JAERI, Tokai. In the present, we have measured Auger and C-K electron spectra from highly excited states produced by 1-3 MeV/u O
(q=3-5) + He collisions, where the highly excited states in Oq+ ions were formed by electron excitation. We have compared and discussed the Auger and C-K electron spectra obtained by electron-capture and electron-excitation processes. It is found that the C-K spectra for high-energy Oq+ ions show relatively low-l states and the Auger spectra also have different structures from those for low-energy highly charged Oq+ ions.
