The escape times of an overdamped Brownian particle confined to a quartic bistable potential is known to be extremely sensitive to the fluctuation correlation time. In the presence of an external Gaussian noise source with fixed variance, the escape times develop a minimum for a certain value of the correlation time—a behavior reminiscent of the so‐called resonant activation phenomenon. The optimal escape conditions are investigated for a wide range of the noise variance.
