Abstract
A bouncelike solution with nonzero energy is used for the explicit calculat ion of the decay rate of an excited state of the asymmetric double-well pot ential. The imaginary part of the energy, which results only from the symme try of the bounce itself, is calculated with the help of the path-integral method. (C) 2001 Published by Elsevier Science B.V.
