We present the nonrelativistic theory of nuclear -decay of arbitrary forbiddenness in the presence of an external plane-wave field. Emphasis is on the question of whether the field is able to break the common selection rules, so that forbidden decays could be significantly enhanced. It turns out that while this is true in principle the required field strength is of the order of the critical one which is far beyond experimental possibilities. Recent claims to the contrary are contested. In particular, in the case of the first-order forbidden decay of 90Sr, we obtain an enhancement which is smaller than a previously published estimate by twenty-four orders of magnitude. 1984.
