Generalized gauge-invariant formulations of the strong-field approximation
Yulian V. Vanne, Alejandro Saenz
The gauge problem in the so-called strong-field approximation (SFA) describing atomic or molecular systems exposed to intense laser fields is investigated. Introducing a generalize…
Feshbach resonances in an ultracold Li and Rb mixture
C. Marzok, B. Deh, C. Zimmermann +4
We report on the observation of five Feshbach resonances in collisions between ultracold Li and Rb atoms in the absolute ground state mixture where both species are in t…
Antiproton collisions with molecular hydrogen
Armin Lühr, Alejandro Saenz
Theoretical antiproton and proton cross sections for ionization and excitation of hydrogen molecules as well as energy spectra of the ionized electrons were calculated in the impac…
A simple parameter-free one-center model potential for an effective one-electron description of molecular hydrogen
Armin Lühr, Yulian V. Vanne, Alejandro Saenz
For the description of an H2 molecule an effective one-electron model potential is proposed which is fully determined by the exact ionization potential of the H2 molecule. In order…
Ionisation of hydrogen molecule in intense ultrashort laser pulses: parallel versus perpendicular orientation
Yulian V. Vanne, Alejandro Saenz
A theoretical comparison of the electronic excitation and ionisation behaviour of molecular hydrogen oriented either parallel or perpendicular to a linear polarised laser pulse is…
Antiproton and proton collisions with the alkali metal atoms Li, Na, and K
Armin Lühr, Alejandro Saenz
Single-electron ionization and excitation cross sections as well as cross sections for excitation into the first excited p state of the alkali metal atoms Li(2s), Na(3s) and K(4s)…
