摘要：

The derivation of the threshold law for ionization of an atom by electron impact is reduced to calculation of the probability of the system survival in the vicinity of the Wannier ridge. The approach is applicable for a small but finite energy excess above the threshold. This reveals the energy range where the Wannier law applies as well as the nature and the character of the deviations outside this region.
