Abstract

Combining several techniques, we propose an efficient and numerically reliable method to perform the quantum number projection and configuration mixing for most general meanfield states, i.e., the Hartree-Fock-Bogoliubov (HFB) type product states without symmetry restrictions. As for the example of calculations, we show the results of the simultaneous parity, number and angular-momentum projection from HFB type states generated from the cranked Woods-Saxon mean-field with a very large basis that is composed of N max = 20 spherical harmonic oscillator shells.
