A Kramers-modified statistical model was applied to study of fission properties of compound nucleus 168Yb formed in heavy ion-induced fusion reactions in an intermediate range of excitation energies. The evaporation residue cross section, fission cross section and the average pre-fission neutron multiplicities were calculated for 168Yb formed in 18O 150Sm reactions and results compared with the experimental data. To calculate these quantities, the effects of temperature and spin K about the symmetry axis have been considered in calculations of the potential energy surfaces and the fission widths. It was shown that the results of the calculations are in good agreement with the experimental data by using values of the temperature coefficient of effective potential and scaling factor of the fission-barrier height equal to and , respectively.
