Isolated-core quadrupole excitation of highly excited autoionizing Rydberg states
M. Génévriez, U. Eichmann
The structure and photoexcitation dynamics of high lying doubly excited states of the strontium atom with high angular momenta are studied in the vicinity of the Sr thresh…
Probing electron and hole co-localization by resonant four-wave mixing in the extreme-ultraviolet
Horst Rottke, Robin Y. Engel, Daniel Schick +11
The extension of nonlinear spectroscopic techniques into the x-ray domain is in its infancy but holds the promise to provide unique insight into the dynamics of charges in photoexc…
Structure and electron dynamics of planetary states of Sr below the Sr and thresholds
Matthieu Génévriez, Christian Rosen, Ulrich Eichmann
In a combined experimental and theoretical study we investigate the and (, ) doubly-excited planetary states of Sr. The experimental spectrum was obt…
Dissecting strong-field excitation dynamics with atomic-momentum spectroscopy
A. W. Bray, U. Eichmann, S. Patchkovskii
Observation of internal quantum dynamics relies on correlations between the system being observed and the measurement apparatus. We propose using the center-of-mass (c.m.) degrees…
Two-electron effects pervading the formation of highly excited neutral atoms in the break-up of strongly driven H
A. Emmanouilidou, D. Tchitchekova, C. Lazarou +1
We present the first theoretical treatment of the formation of highly excited neutral H atoms (H) for strongly driven H. This process, with one electron ionizing and on…
Fano Lineshapes Revisited: Symmetric Photoionization Peaks from Pure Continuum Excitation
U. Eichmann, T. F. Gallagher, R. M. Konik
In a photoionization spectrum in which there is no excitation of the discrete states, but only the underlying continuum, we have observed resonances which appear as symmetric peaks…
