摘要：

Based upon the exact numerical solution of the complex quasienergy problem for a 3-dimensional short-range potential as well as upon analytical evaluations, we demonstrate for any finite frequency omega that the action of an ultra-intense laser field (with electric vector F(omegat)) on a weakly bound atomic system may be described by the cycle-averaging of results for an instantaneous static electric field of strength /F(omegat)/.
