Positronium breakup versus hydrogen ionization in collisions with fast charged projectiles: a comparative study
B. Najjari, S. F. Zhang, X. Ma +1
We perform a comparative study of the breakup of positronium and ionization of atomic hydrogen by projectile-nuclei in the weak perturbation collision regime, $Z_p e_0^2/\hbar \ll…
Fragmentation of the He dimer by relativistic highly charged projectiles in collisions with small kinetic energy release
B. Najjari, S. F. Zhang, X. Ma +1
We study theoretically the fragmentation of the helium dimer, He, into singly charged ions in collisions with relativistic highly-charged projectiles. We discuss the main m…
Probing the helium dimer by relativistic highly-charged projectiles
B. Najjari, Z. Wang, A. B. Voitkiv
We study the fragmentation of He dimers into He ions by relativistic highly-charged projectiles. It is demonstrated that the interaction between an ultrafast projectile wit…
Photo ionization of an atom passed through a diffraction grating
S. F. Zhang, B. Najjari, X. Ma +1
We consider photo ionization of an atom which, due to passing through a diffraction grating, is prepared in a multi-site state possessing a periodic space structure with alternatin…
Probing atomic 'quantum grating' by collisions with charged projectiles
S. F. Zhang, B. Najjari, X. Ma +1
The wave function of an atom passed through a diffraction grating acquires a regular space structure and the interaction of another particle with this atom can be thought of as sca…
Ion-lithium collision dynamics studied with an in-ring MOTReMi
D. Fischer, D. Globig, J. Goullon +12
We present a novel experimental tool allowing for kinematically complete studies of break-up processes of laser-cooled atoms. This apparatus, the 'MOTReMi', is a combination of a m…
