... labels the total number of excitations of the wave function More precisely n − 1 is the total number of excitations in either the radial or angular directions. • Note: For a general radial potential the energy of the wave depends on wether the excitation is in the angular or radial direction. Thus t ...

... This means that the kinetic energy of an electron must exceed 20 M eV if it is to be inside a nucleus. Experiments show that the electrons emitted by certain unstable nuclei never have more than a small fraction of this energy, from which we conclude that nuclei cannot contain electrons. The electro ...

... Periodic Table The Pauli exclusion principle states that only one electron may be in each quantum state: Only one electron at a time may have a particular set of quantum numbers, n, , m , and ms. Once a particular state is occupied, other electrons are excluded from that state. Therefore, if electro ...

Tight binding

In solid-state physics, the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method used in chemistry. Tight-binding models are applied to a wide variety of solids. The model gives good qualitative results in many cases and can be combined with other models that give better results where the tight-binding model fails. Though the tight-binding model is a one-electron model, the model also provides a basis for more advanced calculations like the calculation of surface states and application to various kinds of many-body problem and quasiparticle calculations.
