  We study the possibility of forming the false vacuum bubble nucleated within
the true vacuum background via the true-to-false vacuum phase transition in
curved spacetime. We consider a semiclassical Euclidean bubble in the Einstein
theory of gravity with a nonminimally coupled scalar field. In this paper we
present the numerical computations as well as the approximate analytical
computations. We mention the evolution of the false vacuum bubble after
nucleation.
