Formation of ultracold (7)Li(85)Rb molecules in the lowest triplet electronic state by photoassociation and their detection by ionization spectroscopy.
We report the formation of ultracold (7)Li(85)Rb molecules in the a(3)Σ(+) electronic state by photoassociation (PA) and their detection via resonantly enhanced multiphoton ionization (REMPI). With our dual-species Li and Rb magneto-optical trap apparatus, we detect PA resonances with binding energies up to ∼62 cm(-1) below the (7)Li 2s (2)S1/2 + (85)Rb 5p (2)P1/2 asymptote. In addition, we use...
متن کاملCollisions of doubly spin-polarized, ultracold 85Rb atoms.
We study the collisions of doubly-spin polarized 85 Rb atoms at milliKelvin temperatures using photoassociation spectroscopy. Because the atoms are spin-polarized, only triplet collisional states are formed. This leads to pho-toassociation spectra of a particularly simple form, which exhibit clear quantum statistical features. These spectra are analyzed to yield the ground state triplet scatter...
متن کاملCreation of ultracold ^{87}Rb^{133}Cs molecules in the rovibrational ground state.
We report the creation of a sample of over 1000 ultracold ^{87}Rb^{133}Cs molecules in the lowest rovibrational ground state, from an atomic mixture of ^{87}Rb and ^{133}Cs, by magnetoassociation on an interspecies Feshbach resonance followed by stimulated Raman adiabatic passage (STIRAP). We measure the binding energy of the RbCs molecule to be hc×3811.576(1) cm^{-1} and the |v^{''}=0,J^{''}=...

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...
متن کاملObservation of Broad d-Wave Feshbach Resonances with a Triplet Structure.
High partial-wave (l≥2) Feshbach resonance (FR) in an ultracold mixture of ^{85}Rb-^{87}Rb atoms is investigated experimentally aided by a partial-wave insensitive analytic multichannel quantum-defect theory. Two "broad" resonances from coupling between d waves in both the open and closed channels are observed and characterized. One of them shows a fully resolved triplet structure with a splitt...
