英文摘要

The magnetic dipolar splitting of a p-wave Feshbach resonance is governed by the spin-orbital configuration of the valence electrons in the triplet molecular state. We perform high-resolution trap loss spectroscopy on ultracold 6Li atoms to resolve this splitting with sub-milligauss precision. By comparing spin-polarized (|mS| = 1) and spin-mixture (mS = 0) configurations of the triplet state, we observe a clear spin-dependent reversal in the splitting structure, confirmed via momentumresolved absorption imaging. This behavior directly reflects the interplay between electron spin projection mS and orbital angular momentum ml in the molecular states. Our results provide a stringent benchmark for dipole-dipole interaction models and lay the groundwork for controlling the pairing in p-wave superfluid systems.
