Description

A scheme of path integral evaluation based on the saddle-point method was used for the calculation of the probability of hydrogen atom ionization by short photo-pulse. Gained results are compared with additional calculations based on time-dependent perturbation theory and the time-dependent Schroedinger equation solution by means of a finite element method and with the results of the available data based on a discrete variable representation.
