摘要：

A stable symplectic scheme for calculating particle trajectories in time-periodic force fields based on the Floquet technique and split-operator method is described. The dynamics of a three-dimensional hydrogen atom under the action of an external linearly polarized microwave electric field is studied in a numerical experiment. Under conditions of the implemented dynamical chaos, features in the evolution of angular momentum L(t) of a Rydberg electron (RE) that do not meet the assumptions of traditional theoretical approaches for describing light-induced diffusion ionization of the RE are revealed.
