    "abstract": "It has been suggested that chaotic motion inside the nucleus may\nsignificantly limit the accuracy with which nuclear masses can be calculated.\nUsing a power spectrum analysis we show that the inclusion of additional\nphysical contributions in mass calculations, through many-body interactions or\nlocal information, removes the chaotic signal in the discrepancies between\ncalculated and measured masses. Furthermore, a systematic application of global\nmass formulas and of a set of relationships among neighboring nuclei to more\nthan 2000 nuclear masses allows to set an unambiguous upper bound for the\naverage errors in calculated masses which turn out to be almost an order of\nmagnitude smaller than estimated chaotic components.",
