Abstract

In this paper, we propose an improved method to curtail the time consumption of calculation within the adiabatic theory for the photomomentum distribution (PD) of hydrogen and argon atoms. The method is then extended for threedimensional PD induced by circularly polarized laser. The study is an extension of the work [Phys. Rev. A 92, 043402 (2015)] and a direct comparison of calculating efficiency based on that work is made. The hydrogen and argon atoms exposed to half-cycle laser pulses are used for illustration the applicability of the improved program. The results shows significant reduction in calculation time as well as good consistence between the current results and previous studies.
