Abstract

The assisted tunneling of a wave packet between square one-dimensional barriers is treated analytically. The survival probability is calculated exactly for a potential mimicking a constant electric field with arbitrary time dependence. The pole spectrum of the properly normalized unperturbed wave functions determines the decay time. The tunneling probability is enhanced by the perturbation. The results are exemplified for a simplified model of nuclear $α$ decay.
