Nuclear level density (NLD) is studied within a microscopic approach, which is derived based on the exact thermal pairing (EP) of the pairing Hamiltonian for the truncated single-particle levels around the Fermi surface in combination with the independent-particle model (IPM) for the single-particle levels outside the truncated space [1]. The numerical calculations are carried out for various even-even nuclei, whose experimental data are available. The results obtained show that EP is indeed very important for the valid description of NLD in the low and intermediate regions of excitation energy.
