Intermanifold similarities in partial photoionization cross sections of helium
Tobias Schneider, Chien-Nan Liu, Jan-Michael Rost
Using the eigenchannel R-matrix method we calculate partial photoionization cross sections from the ground state of the helium atom for incident photon energies up to the N=9 manif…
A quasi classical approach to electron impact ionization
Tihamer Geyer, Jan M. Rost
A quasi classical approximation to quantum mechanical scattering in the Moeller formalism is developed. While keeping the numerical advantage of a standard Classical--Trajectory--M…
Resonant enhancements of high-order harmonic generation
C. Figueira de Morisson Faria, R. Kopold, W. Becker +1
Solving the one-dimensional time-dependent Schrödinger equation for simple model potentials, we investigate resonance-enhanced high-order harmonic generation, with emphasis on the…
Asymmetry of the natural line profile for the hydrogen atom
L. N. Labzowsky, D. A. Solovyev, G. Plunien +1
The asymmetry of the natural line profile for transitions in hydrogen-like atoms is evaluated within a QED framework. For the Lyman-alpha absorption transition in neutral h…
