We derive an exact expression for the static bounce solution for {lambda}{phi}{sup 4} theory with broken symmetry. We also propose a new approach to compute a nontrivial real contribution to the generating functional around a classical bounce-type solution avoiding problems due to the presence of a negative eigenvalue. We get this by using the arbitrariness in the mass scale of Wick ordering for the {lambda}{phi}{sup 4} model in dimension {ital d}=1+1.
