J. Liu et al., ATI SPECTRA AND ANGULAR-DISTRIBUTIONS OF THE IONIZED ELECTRONS IN STRONG FIELDS - CLASSICAL APPROACHES, Communications in Theoretical Physics, 25(2), 1996, pp. 129-134
In this paper classical approaches are identified to be a powerful tre
atment in above-threshold ionization processes in strong fields. Numer
ical results are compared with existing theories and some new phenomen
a on angular distributions are showed.
