Jz. Gu et Ys. Ling, INVESTIGATION OF THE INDUCED NUCLEAR-FISSION WITH COORDINATE-DEPENDENT MASS, FRICTION AND TEMPERATURE, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 349(1), 1994, pp. 53-58
The analytical expression of the propagator is obtained by using lie a
lgebra method. The fission rates at the saddle point in both the const
ant and the coordinate-dependent mass, friction and temperature cases
are calculated based on the formulae of the propagator and local appro
ximation. The numerical calculation for Pu-240 shows the fission rates
from our method are reasonable.
