An investigation of the noise activated escape from a metastable state and between attractors in a bistable system has been undertaken. It is demonstrated, both theoretically and by means of digital simulations, that the application of an external time-periodic field can lead to a significant increase in the lifetime (averaged over one period of the field) of a metastable state and in the residence time of a bistable system. In particular, it is shown that these characteristic times can be increased beyond the inverse Kramers rate calculated in the absence of the field. This effect is observed when the frequency of the external field is smaller than the unperturbed Kramers rate.
