The present paper continues a recently published study (devoted to the influence of energy partition in fission and pre-neutron fragment distributions on post-neutron fragment yields) by the investigation of possible correlations between quantities characterizing the pre- and post-neutron fragments. An interesting correlation between the excitation energy of fully accelerated pre-neutron fragments and the kinetic energies of post-neutron fragments is found. The influence of both the energy partition in fission and the pre-neutron fragment distributions on the behaviour of the excitation energy of pre-neutron fragments as a function of the kinetic energy of post-neutron fragments is investigated, too.
