Abstract

The assisted tunneling of a metastable state between barriers is investigated analytically by means of a simplified one-dimensional model. A time dependent perturbation changes the pole spectrum of the wave function introducing a larger decay constant. New insights about the decay of a metastable state are found. The scheme is exemplified for parameters corresponding to the nuclear process of α decay.
