Final-State Spectrum of He after Decay of Tritium Anions T
Alexander Stark, Alejandro Saenz
The final-state spectrum of decaying tritium anions T was calculated. The wavefunctions describing the initial T ground state and the final He states were obtained…
Full two-electron calculations of antiproton collisions with molecular hydrogen
Armin Lühr, Alejandro Saenz
Total cross sections for single ionization and excitation of molecular hydrogen by antiproton impact are presented over a wide range of impact energy from 1 keV to 6.5 MeV. A nonpe…
Mimicking multi-channel scattering with single-channel approaches
Sergey Grishkevich, Philipp-Immanuel Schneider, Yulian V. Vanne +1
The collision of two atoms is an intrinsic multi-channel (MC) problem as becomes especially obvious in the presence of Feshbach resonances. Due to its complexity, however, single-c…
Collisions of antiprotons with hydrogen molecular ions
Armin Lühr, Alejandro Saenz
Time-dependent close-coupling calculations of the ionization and excitation cross section for antiproton collisions with molecular hydrogen ions are performed in an impact-energy r…
Photodissociation of the {HeH} molecular ion
Irina Dumitriu, Alejandro Saenz
The photodissociation cross section of the molecular ion HeH was calculated within the Born-Oppenheimer approximation for a parallel, a perpendicular, and an isotropic orientat…
