    "abstract": "We calculate microscopically total and parity-projected level densities for\n$\\beta$-stable even-even nuclei between Fe and Ge, using the shell model Monte\nCarlo methods in the complete $(pf+0g_{9/2})$-shell. A single-particle level\ndensity parameter $a$ and backshift parameter $\\Delta$ are extracted by fitting\nthe calculated densities to a backshifted Bethe formula, and their systematics\nare studied across the region. Shell effects are observed in $\\Delta$ for\nnuclei with Z=28 or N=28 and in the behavior of $A/a$ as a function of the\nnumber of neutrons. We find a significant parity-dependence of the level\ndensities for nuclei with $A \\alt 60$, which diminishes as $A$ increases.",
