Precise Determination of 6 Li Cold Collision Parameters by Radio-Frequency Spectroscopy on Weakly Bound Molecules

March 1, 2005
Author(s)
M Bartenstein, A Altmeyer, S Riedl, R Geursen, S Jochim, C Chin, J Hecker Denschlag, R Grimm, Andrea Simoni, Eite Tiesinga, Carl J. Williams, Paul S. Julienne
Radio-frequency spectroscopy on weakly bound 6Li_2 molecules determines to high precision the molecular binding energies and the energy splitting between molecular states. By fitting the measurement to a multi-channel quantum scattering model, we determine

Radio-Frequency Transitions on Weakly Bound Ultracold Molecules

January 1, 2005
Author(s)
C Chin, Paul S. Julienne
We show that radio-frequency spectroscopy on weakly-bound molecules is a powerful and sensitive tool to probe molecular energy structure as well as atomic scattering properties. An analytic expression of the rf excitation lineshape is derived, which in

Spontaneous Dissociation of Long-Range Feshbach Molecules

January 1, 2005
Author(s)
T K hler, Eite Tiesinga, Paul S. Julienne
We study the spontaneous dissociation of diatomic molecules produced in cold atomic gases via magnetic field tunable Feshbach resonances. We provide a universal formula for the lifetime of these molecules that relates their decay to the scattering length
