Analysis of the prompt neutron experimental spectra from 252Cf spontaneous fission was carried out to examine the nuclear level density. Prompt fission neutron spectra (PFN) appeared favourable for the experimental estimation of the nuclear level density asymptotic parameter a = alpha-A. Values for alpha were obtained from the systematics of neutron resonance density, analysis of the fissility as a function of excitation energy and from the theoretical prediction based on Woods-Saxon potential.
