Visualization of electronic density [PDF]
Computer Physics Communications, 2015 The spatial volume occupied by an atom depends on its electronic density. Although this density can only be evaluated exactly for hydrogen-like atoms, there are many excellent algorithms and packages to calculate it numerically for other materials.

Electron Wavefunctions and Densities for Atoms [PDF]
Annales Henri Poincaré, 2001 With a special `Ansatz' we analyse the regularity properties of atomic electron wavefunctions and electron densities. In particular we prove an a priori estimate, $\sup_{y\in B(x,R)}|\nabla\psi(y)| \leq C(R) \sup_{y\in B(x,2R)}|\psi(y)|$ and obtain for the spherically averaged electron density, $\widetilde\rho(r)$, that $\widetilde\rho''(0)$ exists and

Electron densities in planetary nebulae [PDF]
The Astrophysical Journal, 1989 A large sample of forbidden lines -[O II], [S II], [Ar IV], and [N I]- have been analyzed to obtain electron densities for 134 planetary nebulae.

Pseudopotentials from electron density [PDF]
Physical Review A, 1996 A method is introduced that allows the construction of pseudopotentials in the density-functional theory. This method is based on a procedure worked out by one of the authors [J. Phys. B 26, 43 (1993); Philos. Mag. B 69, 779 (1994)] for determining Kohn-Sham potentials, one-electron orbitals, and energies from the electron density.

The electron density of Saturn's magnetosphere [PDF]
Annales Geophysicae, 2009 Abstract. We have investigated statistically the electron density below 5 cm−3 in the magnetosphere of Saturn (7–80 RS, Saturn radii) using 44 orbits of the floating potential data from the RPWS Langmuir probe (LP) onboard Cassini. The density distribution shows a clear dependence on the distance from the Saturnian rotation axis (√X2+Y2) as well as on ...

The electron density distribution in CN−, LiCN and LiNC. The use of minimal and extended basis set SCF calculations [PDF]
, 1977 Electron density maps are reported for the CN−ion and the LiCN and LiNC molecules, calculated from molecular wave-functions near the Hartree-Fock limit. The electron density distribution derived from CNDO/ 2 wavefunctions does not resemble the ab initio ...

Appropriate constraints for variational optimization of electronic density matrices and electron densities [PDF]
Proceedings of the National Academy of Sciences, 1982 Euler equations characteristic of the electronic reduced density matrix have previously been obtained by minimizing an energy functional subject to trace constraints 〈 P K 〉 = N , in which N is the number of particles.

Electron density in the magnetosphere [PDF]
Journal of Geophysical Research: Space Physics, 2004 Observations of the electron density ne based on measurement of the upper hybrid resonance frequency by the Polar spacecraft Plasma Wave Instrument (PWI) are available for March 1996 to September 1997, during which time the Polar orbit sampled all MLT values three times.
