High-resolution photoassociation spectroscopy of the 6Li2 A(11Σu+) state
Abstract
We present spectroscopic measurements of seven vibrational levels v=29-35 of the A(11Σu+) excited state of Li2 molecules by the photoassociation of a degenerate Fermi gas of 6Li atoms. The absolute uncertainty of our measurements is ±0.00002 cm-1 (±600 kHz) and we use these new data to further refine an analytic potential for this state. This work provides high accuracy photoassociation resonance locations essential for the eventual high-resolution mapping of the X(11Σg+) state enabling further improvements to the s-wave scattering length determination of Li and enabling the eventual creation of ultracold ground-state 6Li2 molecules.
