Site exclusion principle

An exclusion principle prohibiting more than one particle from occupying a given site or moving in a given direction at a given time. [Pg.489]

Table 4 Ground state Heisenberg energies per site for undistorted polymers (see Refs. 22, 23, 34, 35, and 45 and references therein for other available results). EPV stands for Exclusion Principle Violating infinite summation perturbation theory (see Ref. 34 for more details).

The rate of this reaction is expressed by a pseudo-first order reaction as X k[X]. In diamagnetic substances, however, Ps feels strong repulsive force based on the Pauli s exclusion principle. Hence in crystals Ps will exist in interstitial sites as a Bloch wave, but in substances having density fluctuation it is trapped in open space. Describing the Ps state in the interstitial or in the trapped states by a spherical potential well with infinite height, its zero-point energy is given as. [Pg.338]

The key point is the conservation of the total number of entities for a pair of objects. It translates Pauli s exclusion principle in the following manner The constancy of the total number of objects can be viewed as a fixed number of available sites or allowed energy states. A site (or energy state) can contain one electron or one hole but not both (no electron-hole pairs and no annihilation), because, if we could put more than one electron or hole on one site, the conservation would not be respected. This relies on the assumption that the conservation must... [Pg.193]

Let us discuss the fundamental principle of this mechanism every active site (active intermediate compound) must take part in the synthesis of the products in both reactions, i.e. it must be alternately consumed in them. The situation seems to be rather paradoxical, because the same exclusive active particle must be consumed in both reactions. Therefore, to ensure proper reasoning of this question, some details should be explained using a particular example. [Pg.79]
