Phys. Rev. Lett. 89, 262502 (2002) [4 pages]Exact Level Densities for the Harmonic OscillatorReceived 24 June 2002; published 12 December 2002 The number of levels of a many-fermion system confined by a harmonic-oscillator potential is computed as a function of excitation energy. Because of its exact nature, the formalism accounts for effects of shell structure on the level density. The method is easily extended to a variety of situations as is illustrated with the inclusion of isospin and deformation effects as well as a calculation of the number of spurious states. © 2002 The American Physical Society URL:
