Abstract

We present experimental observations of seven vibrational levels v'=20-26 of the 13Σg+ excited state of Li2 molecules by the photoassociation (PA) of a degenerate Fermi gas of 6Li atoms. For each vibrational level, we resolve the rotational structure using a Feshbach resonance to enhance the PA rates from p-wave collisions. We also, for the first time, determine the spin-spin and spin-rotation interaction constants for this state. The absolute uncertainty of our measurements is pm 0.00002 cm-1 $pm 600$ kHz. We use these new data to further refine an analytic potential for this state.
