| Abstract: | Based on the single-particle levels given by Nilsson,the intrinsic and effective(with collective effects)level density parameters as a function of theexcitation energy for the 186Os, 187Ir, 189Os and 193Au deformation nuclei have been calculatedin the range of the excitation energy up to 150MeV. The calculated fission probabilities Pf(U) are consistent satisfactorily with the experimental data when a nonadiabtic estimation ofthe collective effects was used to calculate the nuclear level density parameters. |
