The recently investigated dynamic model with a shell correction added to the
liquid-drop potential allows the low-energy fission process of heavy nuclei
to be described. The shell-correction term was taken to be the sum of the
Myers and Swiatecki shell energies of two clusters in the compound nucleus
undergoing fission, multiplied by an arbitrary attenuation factor which is
equal to unity at the scission point and vanishes approximately at the 
saddle point.
In this paper, the influence of the shell-energy correction term is studied,
with special reference to the effect of its attenuation factor on results such 
as the mass distribution. For a vanishing shell correction the mass distribution
is symmetric, whereas a full shell correction ( attenuation factor equal to 
unity everywhere ) yields the most asymmetric mass distribution.
