Description

We evaluate both the vacuum decay rate at zero temperature and the finite temperature nucleation rate for the (λ/4! φ4 + σ/6! φ6)3D model. Using the thin-wall approximation, we obtain the solution for the model and we were also able to give the approximate eigenvalue equations for the bounce. (author)
