Diatomic molecular anions of alkali-metal and alkaline-earth-metal atoms
Sana Akkari, Hela Ladjimi, Wissem Zrafi +3
Studies of anions are inherently more challenging than investigations of neutrals and cations because of the diffuse and weakly bound character of an anionic electron. Here, we pre…
Hyperfine-to-rotational energy transfer in ultracold atom-molecule collisions
Yi-Xiang Liu, Lingbang Zhu, Jeshurun Luke +7
Energy transfer between different mechanical degrees of freedom in atom-molecule collisions has been widely studied and largely understood. However, systems involving spins remain…
Ab initio electronic structure and prospects for the formation of ultracold calcium--alkali-metal-atom molecular ions
Wissem Zrafi, Hela Ladjimi, Halima Said +2
Experiments with cold ion-atom mixtures have recently opened the way for the production and application of ultracold molecular ions. Here, in a comparative study, we theoretically…
Spectroscopic properties of the molecular ions BeX^+ (X=Na, K, Rb): Forming cold molecular ions from an ion-atom mixture by stimulated Raman adiabatic process
Hela Ladjimi, Dibyendu Sardar, Mohamed Farjallah +5
In this theoretical work, we calculate potential energy curves, spectroscopic pa- rameters and transition dipole moments of molecular ions BeX^+ (X=Na, K, Rb) composed of alkaline…
