Abstract
We show that the Duru-Kleinert fixed energy amplitude leads to the pat h integral for the propagation amplitude in the closed FRW quantum cos mology with scale factor as one degree of freedom. Then, using the Dur u-Kleinert equivalence of corresponding actions, we calculate the tunn eling rate, with exact prefactor, through the dilute-instanton approxi mation to the first order in h.
