We study odd-even mass staggering of nuclei, also called pairing gaps, usinga Skyrme self-consistent mean-field theory and a numerically exact treatment ofthe pairing Hamiltonian. We find that the configuration-space Monte Carlomethod proposed by Cerf and Martin offers a practical computational procedureto carry out the numerical solutions in large-dimensional model spaces.Refitting the global strength of the pairing interaction for 443 neutronpairing gaps in our number-conserving treatment, we find the correction to thepairing correlation energies and pairing gaps to have rms values of 0.6 MeV and0.12 MeV, respectively. The exact treatment provides a significant improvementin the fit to experimental gaps, although it is partially masked by a largerrms error due to deficiencies in other aspects of the theory such as themean-field energy functional.
