    "abstract": "We study the influence of the scheme for the correction for spurious\ncenter-of-mass motion on the fit of effective interactions for self-consistent\nnuclear mean-field calculations. We find that interactions with very simple\ncenter-of-mass correction have significantly larger surface coefficients than\ninteractions for which the center-of-mass correction was calculated for the\nactual many-body state during the fit. The reason for that is that the\neffective interaction has to counteract the wrong trends with nucleon number of\nall simplified schemes for center-of-mass correction which puts a wrong trend\nwith mass number into the effective interaction itself. The effect becomes\nclearly visible when looking at the deformation energy of largely deformed\nsystems, e.g. superdeformed states or fission barriers of heavy nuclei.",
