Microscopic calculation of symmetry projected nuclear level densities
Abstract
We present a quantum Monte Carlo method with exact projection on parity and angular momentum that is free of sign-problems for seniority-conserving nuclear interactions. This technique allows a microscopic calculation of angular momentum and parity projected nuclear level densities. We present results for the 55Fe, 56Fe and 57Fe isotopes. Signatures of the pairing phase transition are observed in the angular momentum distribution of the nuclear level density.
