Abstract
Using a nonperturbative scattering theory, we study the photoelectronangular distributions (PADs) of Kr atoms irradiated by an infinite sequenceof intense single-cycle pulses of circular polarization. We demonstrate theinversion asymmetry of PADs and the dependence of PADs on thecarrier-envelope phase of the single-cycle pulses. The inversion asymmetry iscaused by the interference between transition channels where the differentchannels are characterized by different combinations of absorbed-photonnumbers in the ionization process. Our results provide a possible method todetermine the value of carrier-envelope phase by the detected PADs.
