The formulae of calculation of the nuclear level density based on the theory of superconductivity are presented. Special attention is paid to the dependence of the level density on the angular momentum. The moment of inertia is evaluated using the cranking model. For a deformed nucleus, the ...
Fig. 2. (a) The electron density (top) and the Laplacian of the electron density (bottom) for the Li 2S state (UHF/6–31 G). The Valence Shell Charge Concentration (VSCC)11 extends from 2.2 to 3.8 au from the Li nucleus. Contours are drawn at intervals of ± (2,4,8)·10n,–...
The density of a material is defined as its mass per unit volume. The symbol of density is ρ (the Greek letter rho).FormulaMathematically:where:ρ is the density, m is the mass, V is the volume.Different materials usually have different densities, so density is an important concept regard...
(15) For normalized proton (neutron) density distributions, the denominator becomes Z (N) of the nucleus. Also, we can calculate the neutron-skin thickness ( respect to the proton density as, np ) that represents the extension of the neutron density with �np(A, Z, N ) = �...
theimproved nuclear density modeland the condition of the nuclear momentum conservation, we derived the formula of the nuclear effect parameter formula for the nuclear gluon distribution function,in which our established connection between the nuclear density and the mean binding energy in nucleus is ...
For the most simple model of the nucleus, a system of independent fermions with equally spaced single-particle levels, the density of particle-hole states is calculated. The exact result, obtained by combinatorial methods, is compared with a level-density formula which is derived by means of ...
where the first term is the classical energy, encompassing kinetic energy, and various types of classical Coulomb energies between nucleus-nucleus, nucleus-electron, and electron-electron, calculated by using the MC-SCF method (usually the complete active space self-consistent field, CASSCF, method)...
