Abstract

We have observed the formation of ground-state Na{sub 2} molecules via the spontaneous decay of excited molecules created by the photoassociation of ultracold atoms. We measure the binding energies of molecules created in three hyperfine components of the lowest singlet and triplet potentials of Na{sub 2} by two different methods. Two of the features are purely triplet a {sup 3}{sigma}{sub u}{sup +} (v=15) (quasibound) states that have not been previously observed, while the third is a mixed X {sup 1}{sigma}{sub g}{sup +}-a {sup 3}{sigma}{sub u}{sup +} state. The molecules are detected with high-resolution cw laser ionization techniques and binding energies are measured to within 10 MHz.

Experimental Investigation of Ultracold Atom-Molecule Collisions

Journal Article Staanum, Peter; Kraft, Stephan; Lange, Joerg; ... - Physical Review Letters

Ultracold collisions between Cs atoms and Cs{sub 2} dimers in the electronic ground state are observed in an optically trapped gas of atoms and molecules. The Cs{sub 2} molecules are formed in the triplet ground state by cw photoassociation through the outer well of the 0{sub g}{sup -}(P{sub 3/2}) excited electronic state. Inelastic atom-molecule collisions converting internal excitation into kinetic energy lead to a loss of Cs{sub 2} molecules from the dipole trap. Rate coefficients are determined for collisions involving Cs atoms in either the F=3 or F=4 hyperfine ground state, and Cs{sub 2} molecules in either highly vibrationally excitedmore »« less

Triplet-singlet conversion in ultracold Cs{sub 2} and production of ground-state molecules

Journal Article Bouloufa, Nadia; Aymar, Mireille; Dulieu, Olivier; ... - Physical Review. A

We propose a process to convert ultracold metastable Cs{sub 2} molecules in their lowest triplet state into (singlet) ground-state molecules in their lowest vibrational levels. Molecules are first pumped into an excited triplet state, and the triplet-singlet conversion is facilitated by a two-step spontaneous decay through the coupled A {sup 1{Sigma}}{sub u}{sup +}-b {sup 3{Pi}}{sub u} states. Using spectroscopic data and accurate quantum chemistry calculations for Cs{sub 2} potential curves and transition dipole moments, we show that this process competes favorably with the single-photon decay back to the lowest triplet state. In addition, we demonstrate that this conversion process representsmore »« less

Formation of ultracold Cs{sub 2} molecules through the double-minimum Cs{sub 2} 3 {sup 1}{sigma}{sub u}{sup +} state

Journal Article Pichler, Marin; Stwalley, William; Beuc, Robert; ... - Physical Review. A

We present a simple model of ultracold cesium dimer formation in which the photoassociation into rovibrational levels of the double-minimum Cs{sub 2} 3 {sup 1}{sigma}{sub u}{sup +} state above its internal barrier enables spontaneous or stimulated emission into the lowest rovibrational levels of the Cs{sub 2} 1(X) {sup 1}{sigma}{sub g}{sup +} ground electronic state. The transition dipole moment should be sufficiently large for observation of such spectral transitions. The use of the Cs{sub 2} 3 {sup 1}{sigma}{sub u}{sup +} double-minimum potential could be extended to molecular Bose-Einstein condensates in which an optical trap can be employed for trapping of bothmore » atomic and molecular species.« less

Short-pulse photoassociation in rubidium below the D{sub 1} line

Journal Article Koch, Christiane; Kosloff, Ronnie; Masnou-Seeuws, Francoise - Physical Review. A

Photoassociation of two ultracold rubidium atoms and the subsequent formation of stable molecules in the singlet ground and lowest triplet states is investigated theoretically. The method employs laser pulses inducing transitions via excited states correlated to the 5S+5P{sub 1/2} asymptote. Weakly bound molecules in the singlet ground or lowest triplet state can be created by a single pulse while the formation of more deeply bound molecules requires a two-color pump-dump scenario. More deeply bound molecules in the singlet ground or lowest triplet state can be produced only if efficient mechanisms for both pump and dump steps exist. While long-range 1/R{supmore »« less

Two-photon photoassociation spectroscopy of an ultracold heteronuclear molecule

Journal Article Dutta, Sourav; Pérez-Ríos, Jesús; Elliott, D.; ... - Physical Review A

In this work, we report on two-photon photoassociation (PA) spectroscopy of ultracold heteronuclear LiRb molecules. This is used to determine the binding energies of the loosely bound levels of the electronic ground singlet and the lowest triplet states of LiRb. We observe strong two-photon PA lines with power broadened linewidths greater than 20 GHz at relatively low laser intensity of 30W/cm2. The implication of this observation on direct atom to molecule conversion using stimulated Raman adiabatic passage is discussed and the prospect for electronic ground-state molecule production is theoretically analyzed.
