Abstract
The resonance states of a periodically driven barrier potential are investi gated. We show that narrow shape-type resonances evolve from overlapping re sonances of a static barrier as a result of an increase of the field amplit ude. These shape-type resonances are associated with the field-induced barr ier transparency phenomenon. It is suggested that cross-section experiments in strong laser fields may be used to uncover overlapping resonances. [S10 50-2947(99)01902-2].
