Binding Energies of 6Li p-wave Feshbach Molecules

Abstract

We present measurements of the binding energies of ${}^6$Li p-wave Feshbach molecules formed in combinations of the (F = 1/2, m_F = +1/2), (1), and (F = 1/2, m_F = -1/2), (2), states. The binding energies scale linearly with magnetic field detuning for all three resonances. The relative molecular magnetic moments are found to be $113\pm 7\hat{I}¼$K/G, $111\pm 6\hat{I}¼$K/G and $118\pm 8\hat{I}¼$K/G for the (1)-(1), (1)-(2) and (2)-(2) resonances, respectively, in good agreement with theoretical predictions. Closed channel amplitudes and the size of the p-wave molecules are obtained theoretically from full closed-coupled calculations.
