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…
