Abstract
The ionisation potential of an atom in a laser field is known to be intensity dependent. Previous theories apply only to a non-resonant field. The result is extended to the case of the Nr photon resonance where Nr is any positive integer. The new result contains several new features. Rapid frequency dependence is one and a dependence upon the conditions in which the atom enters the field is another.Keywords
