Abstract
We present a model which allows for the calculation of fragment excitation and
kinetic energy in nuclear fission. The model assumes that fission products
are excited independently according to an exponential distribution function, which
depends on the
Q-value of the reaction and the level density parameter in the
single fragment. We develop the model description
and compare the results
for different fissioning systems from actinium to fermium, and for different
compound reactions, namely spontaneous fission, fission following
thermal neutron capture, and high-energetic reactions with experimental data.
