摘要

【正】 An analytical expression of the propagator is obtained by using Lie algebramethod.The fission rates at the saddle point in both constant and coordinate-dependentmass,friction and temperature cases are calculated based on the expression of thepropagator and local approximation.The numerical calculation for ²⁴⁰pu shows thatthe fission rates from our method are reasonable.
