We compute level densities with a nuclear statistical spectroscopy approach. This model is based on the microscopic physics of the interacting shell model. The level density is constructed by means of a sum of binomial distributions. The partial densities correspond to different configurations of the valence space. The individual binomial parameters fit the exact configuration moments. Calculations of level densities for sd-shell nuclides show the model to work well, when compared to exact calculations with full-diagonalization shell model.
