Hartree-Fock-Bogoliubov calculations with Gaussian expansion method

An algorithm of the Hartree-Fock-Bogoliubov (HFB) calculations using the Gaussian expansion method is newly developed. By this method we can handle various effective interactions on the same footing, and the wave-function asymptotics, either exponential or oscillatory ones, are efficiently handled even for finite-range interactions. In the previous study we have shown by the spherical Hartree-Fock calculations that the shell structure around N=16 and 32 depends on the effective interactions (e.g. the Skyrme, the Gogny interaction and M3Y-type interactions) and their parameters, to an appreciable extent. Applying the HFB calculations, influence of the pair correlations on the magicity of N=16 and 32 will be discussed.
