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 …
