The nuclear level density (NLD) of $^{56}$Fe was studied using the exact pairing plus independent particle model (EP + IPM) [1], and the results were compared with experimental data for a range of quadrupole deformation parameters, either assumed or obtained from theoretical and experimental sources [2, 3]. The results indicate that quadrupole deformation, represented by the parameter $\beta_2$, significantly influences the NLD, particularly at low excitation energies. This influence is primarily attributed to changes in the nuclear potential shape, which affect the distribution and density of energy levels. [1] N. Quang Hung*, N. Dinh Dang, and L. T.
