Quantum mechanics of multielectronic atoms and ions A. I. Laptukhov, V. A. Laptukhov Pushkov’s Institute of Terrestrial Magnetism, Ionosphere and Radiowaves Propagation (IZMIRAN), Troitsk, 142190, Russia E-mail: laptuhov@izmiran.ru 1, 2012 For account of a spectrum of power levels of multielectronic atoms, the system of the equations of a hydrodynamical type is written down, from which the Shredinger’s equation as individual (not general) decision follows. <...> Within the framework of this system of the equations for atom He and two-electronic ions such as Li+, Be++, B+++ etc., the power levels of the basic condition of atoms are designed which with an error are less or about one percent will be coordinated to experimental data. <...> PACS: 32.10.Hq, 32.10.-f Keywords: quantum mechanics, account of multielectronic atoms, ions, potentials of ionization. <...> Для расчета спектра энергетических уровней многоэлектронных атомов зшшсана система уравнений гидродинамического типа, из которой следует уравнение Шрёдинг ер а как частное решение. <...> Принцип Паули является логическим следствием рассматриваемой теории, а не дополнительным постулатом! <...>
