Abstract (EN)

The level density parameters (level density parameter a and energy shift parameter delta) basedon back-shifted Fermi gas model have been determined for 1136 nuclei for which complete levelscheme is available. Level density parameter is calculated by using semi-classical single particle leveldensity, which can be obtained analytically through spherical harmonic oscillator potential. This methodalso enables to analyze the Coulomb potential's effect on the level density parameter. The dependenceof this parameter on energy has been also investigated. Another parameter, delta, is determined byfitting of the experimental level scheme and the average resonance spacings for 289 nuclei. Onlylevel scheme is used for optimization procedure for remaining 847 nuclei. Level densities for somenuclei have been calculated by using these parameter values. The obtained results have beencompared with the experimental level scheme and the resonance spacing data.
