With the one-photon photoassociation measurements complete, we now expand our binding energy measurements to the ground state. An accurate model of the electronic ground state potential is essential for accurate prediction of interspecies Feshbach resonances and can also be used to calculate interspecies scattering lengths.

Fano profiles in two-photon photoassociation spectra
Faraday Discussions, 2009In this article we derive the lineshapes observed in two-photon photoassociation spectrocopy of molecules using an effective Hamiltonian adapted from previous work in atomic physics. The lineshape is decomposed in terms of sums and products of Breit-Wigner and Fano profiles, which we associate with physical absorption and emission processes, and to ...

Photoassociation is an important tool in the field of ultracold AMO physics [38]. It extends the fantastic progress of precision spectroscopy in ultracold atoms into the molecular domain. The technique allows precise measurements of molecular potentials useful for characterising atomic interactions and for studies of quantum chemistry [46 ...

Laser-induced photoassociation of ultracold sodium atoms
Physical Review Letters, 1987We present the theory of laser-induced radiative association in terms of a scattering resonance formalism and apply this theory to the specific case of Na atom collisions at a temperature of 10 mK. Use of ultracold atoms permits a new kind of high-resolution free-bound spectroscopy for the study of near-threshold collisions and excited-state energy ...

Photoassociation in Cold Atoms via Ladder Excitation
Physical Review Letters, 2007We explore 2-color photoassociative ionization in cold Rb vapor and present experimental evidence that the molecular ions are produced from the stepwise excitation of a ladder of molecular states. We also explore a new process, dubbed photoassociative-dissociative ionization, by which atomic ions are created by excitation through a ladder of molecular ...

Local control theory applied to molecular photoassociation
The Journal of Chemical Physics, 2007Local control theory (LCT) is employed to achieve molecular photoassociation with shaped laser pulses. Within LCT, the control fields are constructed from the response of the system to the perturbation which makes them accessible to a straightforward interpretation. This is shown regarding the ground-state collision of H+F and H+I atoms.

Two-photon photoassociation spectroscopy of heteronuclear YbRb
Physical Chemistry Chemical Physics, 2011We report on the spectroscopic investigation of vibrational levels in the electronic ground state of the heteronuclear molecule (176)Yb(87)Rb. Using two-photon photoassociation spectroscopy in a laser-cooled mixture of (176)Yb and (87)Rb we are able to determine the binding energies of weakly-bound vibrational levels.
