It is well known that the kinetic energy of a system of N noninteracting particles in an external field V(r) in the nondegenerate ground state is a universal functional of the particle density 蟻(r) [1]. However, the explicit form of this functional is defined only for a certain class...
We derive a simple expression for the correlation part of the kinetic energy of an inhomogeneous electron gas from density-functional theory. We show that in the local density approximation, this expression reduces to the virial theorem result txc=3vxc-4εxc. We also derive the correction for ...
We study the metal-surface jellium model with different approximations for the kinetic-energy density-functional model including the gradient expansions and other fully nonlocal functional models. Instead of the approximated variational method used in the previous analysis of the problem, we get the exa...
Tags Electron Energy Kinetic Kinetic energy In summary, when ultraviolet light with a wavelength of 60.0 nm shines on a gas of hydrogen atoms in their ground states, some of the atoms are ionized, freeing electrons. To determine the kinetic energy of these electrons, the equation En = n2h2...

The development of the kinetic theory of gases is a famous and well-documented episode in the history of science. This change, they claim, caused many scientists to...
We report measurements of the kinetic energy ( E k ) distributions of O produced by low-energy electron impact (5.5–19.5 eV) on disordered multilayers of O 2 physisorbed on a polycrystalline Pt substrate. The results confirm that dissociative electron attachment (DEA) proceeds via the formation...
Electron spin relaxation (ESR) in the gas phase is treated using the Waldman—Snider kinetic equation for polyatomic gases. Although only the simplest case, that of 2Σ molecules, is treated here, it is already sufficient to bring out all of the relevant features and to illustrate the ...
By means of a Subshell model the density matrix and its diagonal element are expressed in terms of Subshell electron densities. As a result, the exact kinetic-energy density is obtained in the form of Weizsacker-type contributions plus extra terms resulting from angular derivatives. It is shown...
