A precise scan of the previously discovered laser-induced transition (n, l) = (37, 35) → (38, 34) in p̄He+ revealed a doublet structure with a separation of ΔνHF = 1.70 ± 0.05 GHz. This new type of "hyperfine" splitting is ascribed to the interaction of the antiproton orbital angular momentum and the electron spin.
