    "abstract": "In this article, we study an antithesis of the homogeneous Fermi system\n(jellium model) namely a single multielectron atom using the sea-boson\napproach. This system in addition to having a small number of electrons(finite\nsystem) is also extremely inhomogeneous. This means that the plane-wave basis\nis ill-suited to study this system, instead we use a basis consisting of the\neigenfunctions of an electron interacting with the nucleus situated at the\norigin (ideal atom).\n  We compute the energy levels of this system and polarizabilities and compare\nwith the results of other approaches such as Hartree-Fock and pseudopotentials\nfor the former and aysmptotic wavefunctions for the latter and with\nexperiments.",
