Abstract
A simple formula for the ratio of the number of odd- and even-parity states as a function of temperature is derived. This formula is used to calculate the ratio of level densities of opposite parities as a function of excitation energy. We test the formula with quantum Monte Carlo shell model calculations in the -shell. The formula describes well the transition from low excitation energies where a single parity dominates to high excitations where the two densities are equal.
