    "abstract": "We study the quantum-mechanical tunneling phenomenon in models which include\nthe existence of non-equivalent vacua. For such a purpose we evaluate the\neuclidean propagator between two minima of the potential at issue in terms of\nthe quadratic fluctuations over the corresponding instantons. The effect of the\nmulti-instanton configurations are included by means of the alternate\ndilute-gas approximation.",
