The energy spectra of neutrons, protons, and \ensuremathα-particles have been measured from the d+59Co and 3He+58Fe reactions leading to the same compound nucleus, 61Ni. The experimental cross sections have been compared to Hauser-Feshbach model calculations using different input level density models. None of them have been found to agree with experiment. It manifests the serious problem with available level density parametrizations especially those based on neutron resonance spacings and density of discrete levels. New level densities and corresponding Fermi-gas parameters have been obtained for reaction product nuclei such as 60Ni, 60Co, and 57Fe.
