We show that the Duru-Kleinert fixed energy amplitude leads to the path
integral for the propagation amplitude in the closed FRW quantum cosmology
with scale factor as one degree of freedom. Then, using Duru-Kleinert
equivalence of corresponding actions, we calculate the tunneling rate,
with exact prefactor, through the dilute-instanton approximation to
first order in h.
