Partitation of the excitation energy between the fission fragment in spontaneous fission of Cf252

in this thesis experimental data on mass distribution of fission fragments, kinetic energy distribution of fission fragments, neutron avaerage multiplicity distribution of fission fragments, and neutron average emission energy from fission fragments in spontaneous fission of Cf252 were analayzed in order to calculate correlation in neutron average number distribution and correlation in fission fragment average excitation energy distribution. To fulfill this task the most probable charge values for complementary light and heavy fragments in spontaneous fission of Cf252, neutron binding energy of fission fragments and the average gamma ray energy from fission fragments has been estimated. The average fission fragment excitation energy then is estimated. Results of calculations are in satisfactory agreement with corresponding experimental results.
