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…
The collinear helium atom and two-electron ions
Evgeny Z. Liverts, Rajmund Krivec, Nir Barnea
Collinear configurations of the helium-like atomic systems, relevant, e.g., for the quasifree mechanism of the double photoionization of helium, are studied, parameterized by the s…
Averaged electron densities of the helium-like atoms
Evgeny Liverts, Rajmund Krivec
Different kinds of averaging of the wavefunctions/densities of the two-electron atomic systems are investigated. Using the Pekeris-like method, the ground state wave functions …
On detecting Higgs coupling in transitions of light atoms
Rajmund Krivec
In light of the known Higgs mass and the current constraints on the quark-lepton Higgs coupling, we derive conditions for extracting upper limits on the lepton-nucleon Higgs coupli…
Photoionization accompanied by excitation at intermediate photon energies
E. G. Drukarev, E. Z. Liverts, M. Ya. Amusia +2
We calculate the photoionization with excitation-to photoionization ratios for atomic helium and heliumlike ions at intermediate values of the photon energies. The final state inte…
