Two-electron atomic systems. A simple method for calculating the ground state near the nucleus. Some applications
Evgeny Z. Liverts
A simple method of variational calculations of the electronic structure of a two-electron atom/ion, primarily near the nucleus, is proposed. The method as a whole consists of a sta…
Fock expansion for two-electron atoms. High order angular coefficients
Evgeny Z. Liverts, Rajmund Krivec
The Fock expansion, which describes the properties of two-electron atoms near the nucleus, is studied. The angular Fock coefficients with the maximum possible value…
Analytic scattering parameters at low energies
Evgeny Z. Liverts
The scattering of two and more particles at low energies is described by the so called effective-range expansion. The leading terms of this expansion are the scattering length and…
Electrons on sphere in the helium-like atomic systems
Evgeny Z. Liverts
The properties of a special configuration of a helium-like atomic system, when both electrons are on the surface of a sphere of radius , and angle characterizes their positi…
Accurate exponential representations for the ground states of the collinear two-electron atomic systems
Evgeny Z. Liverts, Nir Barnea
In the framework of the study of helium-like atomic systems possessing the collinear configuration, we propose a simple method for computing compact but very accurate wave function…
Small recoil momenta double ionization of He and two-electron ions by high energy photons
Miron Ya. Amusia, Evgeny G. Drukarev, Evgeny Z. Liverts
We calculate various differential and double differential characteristics of ionization by a single photon for H, He and for the two-electron ions with Z=3,4,5 in the region of…
