L.L.2022-04-292022-04-291982-01-01The Journal of Chemical Physics, v. 77, p. 6131-6133.0021-9606http://hdl.handle.net/11449/231078The large Z Thomas-Fermi-Scott-Schwinger expansion for the total nonrelativistic binding energy of a neutral atom is used, together with the Bohr energy formula valid at Z = 1, to construct various Padé approximants among which the two-point [3//3] approximant gives an overall improved representation for the energy for Z from 1 to 290, and very especially for the closed shell values Z = 10, 18, 36, 54, 86, 118, 168, and 290. The presence of oscillatory terms for open shells in the large Z expansion is also confirmed. © 1982 American Institute of Physics.6131-6133engArtigo10.1063/1.4438572-s2.0-36749118160
