Abstract
Stochastic resonance has been examined in a number of systems that have steady states. We examine a dynamical system that allows for the escape of a particle from a potential well, and that is subjected to the combination of a periodic forcing term and noise. We show that in such a system the addition of a small amount of noise can actually increase the average time for the particle to escape from the well. This effect depends on the frequency of the external field and in this sense is a form of stochastic resonance.
