چکیده

On the bases of Bethe and the constant temperature models, the level density parameters have been calculated for the 36Cl, 40K, 60Co and 61Ni nuclei, nucleuses through fitting the complete level schemes in low excitation energy levels. Both calculations reproduce experimental level densities equally well. The spins cut off parameters of the same nuclei have been determined from the analysis of experimental data for spins of low-lying states.
