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…
Highly Accurate Analytic Presentation of Solution of the Schrödinger Equation
E. Z. Liverts, E. G. Drukarev, R. Krivec +1
High-precision approximate analytic expressions for energies and wave functions are found for arbitrary physical potentials. The Schrödinger equation is cast into nonlinear Riccati…
Analytic calculation of energies and wave functions of the quartic and pure quartic oscillators
E. Z. Liverts, V. B. Mandelzweig, F. Tabakin
Ground state energies and wave functions of quartic and pure quartic oscillators are calculated by first casting the Schrödinger equation into a nonlinear Riccati form and then sol…
Two-electron photoionization of endohedral atoms
M. Ya. Amusia, E. Z. Liverts, V. B. Mandelzweig
Using as an example, we demonstrate that static potential of the fullerene core essentially alters the cross section of the two-electron ionization differential in one-…
Wave Functions of Heliumlike Systems in Limiting Regions
E. Z. Liverts, M. Ya. Amusia, E. D. Drukarev +2
We find approximate analytical presentation of the solutions of Schrödinger equation for two-electron system bound by the nucleus, in the space region $r_{1,2…
Calculation of the photoionization with de-excitation cross sections of He and helium-like ions
M. Ya. Amusia, R. Krivec, E. Z. Liverts +1
We discuss the results of the calculation of the photoionization with de-excitation of excited He and helium-like ions Li and B at high but non-relativistic photon ene…
