Thomas-Fermi atom model

[′täm·əs ′fer·mē ′ad·əm ‚mäd·əl]
(atomic physics)
A method of approximating the electrostatic potential and the electron density in an atom in its ground state, in which these two quantities are related by the Poisson equation on the one hand, and on the other hand by a semiclassical formula for the density of quantum states in phase space.
