摘要：

The photoelectron spectra and angular distribution of single and doubly ionized ions of helium in an intense laser field was calculated. The energy and angular distributions of He+were found similar to those of the typical single-electron atom-hydrogen. The distributions of He2+differed from He+in its slowly decreasing energy spectra, flat angular distribution and the shift of the maximum of the angular distribution.
