TITLE=/ Partition of total excitation energy between fragment pairs
in asymmetric and symmetric fission modes /;
PURPOSE=/ To reveal how the degrees of fragment deformation at
scission are correlated to the different scission
configurations of the two fission modes and how the total
excitation energies are shared between fragment pairs in
each fission mode /;
