Abstract: An extended inflation model, in which the inflaton field is nonminimally coupled to the gravity, is discussed. It is shown that the nucleation rate of bubbles, during a phase transition in the inflaton field, can increase as the transition proceeds for a wide range of parameters of the inflaton potential. The bounce action for three possible cases—the strong gravity regime, the thick-walled Coleman-De Luccia bubbles and the thin-walled bubbles—is evaluated. The resulting bubble distribution for all the cases is shown to be in conformity with cosmological constraints for ω<500.
