Nuclear level densities in 94,96,98Mo and 160,162,164Dy isotopes are calculated using the single particle spectrum obtained with the Woods-Saxon potential. The level-density parameters, spin cut-off factors, and moments of inertia are studied. Using the available experimental data at low excitation energies, the collective enhancement of the level densities are calculated and compared with those of the phenomenological model. In Mo isotopes, this semiempirical calculations agree better with the experiments in comparison to the phenomenological model assuming a spherical shape.
