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 determine the spin-spin and spin-rotation interaction constants for this state. The absolute uncertainty of our measurements is ±0.00002 cm1 (±600 kHz). We use this data to further refine an analytic potential for this state.
