Phys. Rev. C 53, 172–175 (1996)Approximate particle number projection for finite range density dependent forcesReceived 26 May 1995; published in the issue dated January 1996 The Lipkin-Nogami method is generalized to deal with finite range density dependent forces. New expressions are derived and realistic calculations with the Gogny force are performed for the nuclei 164Er and 168Er. The sharp phase transition predicted by the mean field approximation is washed out by the Lipkin-Nogami approach. A much better agreement with the experimental data is reached with the new approach than with the Hartree-Fock-Bogoliubov one, especially at high spins. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
