Formation of ultracold LiRb molecules by photoassociation near the Li(2 s 2 S 1/2 ) + Rb(5 p 2 P 1/2 ) asymptote

Study of coupled states for the ( 4 s 2 ) 1 S + ( 4 s 4 p ) 3 P asymptote of Ca

Production of ultracold ground-state LiRb molecules by photoassociation through a resonantly coupled state

We report on a resonantly coupled 2(1)-4(1) photoassociation resonance in LiRb. This pair of states displays interesting decay physics that hint at interference-like effects caused by two different decay paths. We observe decay to predominantly X 1 + v = 43, with significant numbers of molecules produced in X 1 + v = 2−12. This photoassociation resonance also produces ∼300 X 1 + v = 0 J = 0 mol...

Experimental Studies of LiRb: Spectroscopy and Ultracold Molecule Formation by Photoassociation

Dutta, Sourav Ph.D., Purdue University, December 2013. Experimental Studies of LiRb: Spectroscopy and Ultracold Molecule Formation by Photoassociation. Major Professor: Yong P. Chen. Heteronuclear polar molecules have recently attracted enormous attention owing to their ground state having a large electric dipole moment. The long range anisotropic dipole-dipole interaction in such systems is th...

Interference effects in hyperfine induced 2 s 2 s 3 P 0 , 3 P 2 → 2 s 2 1 S 0 transitions of Be - like ions

The hyperfine induced 2s2p P0, P2 → 2s 2 S0 E1 transition probabilities of Be-like ions were calculated using grasp2K based on multi-configuration Dirac-Fock method and HFST packages. It was found that the hyperfine quenching rates are strongly affected by the interference for low-Z Be-like ions, especially for 2s2p P0 → 2s2 S0 transition. In particular, the trends of interference effects with ...
