    "abstract": "Nuclear mass autocorrelations are investigated as a function of the number of\nnucleons. The fluctuating part of these autocorrelations is modeled by a\nparameter free model in which the nucleons are confined in a rigid sphere.\nExplicit results are obtained by using periodic orbit theory. Despite the\nsimplicity of the model we have found a remarkable quantitative agreement of\nthe mass autocorrelations for all nuclei in the nuclear data chart. In order to\nachieve a similar degree of agreement for the nuclear masses themselves it is\nnecessary to consider additional variables such as multipolar corrections to\nthe spherical shape and an effective number of nucleons. Our findings suggest\nthat higher order effects like nuclear deformations or residual interactions\nhave little relevance in the description of the fluctuations of the nuclear\nautocorrelations.",
