Abstract
First order phase transitions in general proceed via nucleation of
bubbles. A theoretical basis for the calculation of the nucleation rate
is given by the homogeneous nucleation theory of Langer and its field
theoretical version of Callan and Coleman. We have calculated the
nucleation rate beyond the thin wall approximation by expanding the
bubble solution and the fluctuation determinant in powers of the
asymmetry parameter. The result is expressed in terms of physical model
parameters.
