Using Nilsson single-panticle level schemes as input, we have calcnlated pantial state densities for excited proton-neutron configuration with specified particle-hole numbers. The recursion relation method used is general and free of any mathematical approximations. Results are given for nuclides in the Sn region and for several Pb isotopes. The strong shell effects in these nuclei are clearly reflected in their state densities. The results are compared to densities obtained from the equidistant-spacing model. This model not only fails completely at low excitation energies as expected, but ii also disagrees in several cases with the average behavior of the realistic densities at higher energies. (auth)
