Stopping power of antiprotons in H, H2, and He targets
Armin Lühr, Alejandro Saenz
The stopping power of antiprotons in atomic and molecular hydrogen as well as helium was calculated in an impact-energy range from 1 keV to 6.4 MeV. In the case of H2 and He the ta…
Collisions of low-energy antiprotons with molecular hydrogen: ionization, excitation and stopping power
Armin Lühr, Alejandro Saenz
A time-dependent coupled-channel approach was used to calculate ionization, excitation, and energy-loss cross sections as well as energy spectra for antiproton and proton collision…
Interaction of antiprotons with Rb atoms and a comparison of antiproton stopping powers of the atoms H, Li, Na, K, and Rb
Armin Lühr, Nicolas Fischer, Alejandro Saenz
Ionization and excitation cross sections as well as electron-energy spectra and stopping powers of the alkali metal atoms Li, Na, K, and Rb colliding with antiprotons were calculat…
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…
