Regularization of Multi-Reference Energy Density Functional Calculations
M. Bender1, T. Duguet2, P. -H. Heenen, D. Lacroix3

We report the first application of a recently proposed regularization procedure for multi-reference energy density functionals, which removes spurious divergent or non-continuous contributions to the binding energy, to a general configuration mixing. As an example, we present a calculation that corresponds to the particle-number and angular momentum projection of axially symmetric time-reversal invariant quasiparticle vacua of different quadrupole deformation for the nucleus O18. The SIII parameterization of the Skyrme energy functional is used.
