In a Λ16O γ-ray spectroscopy experiment with HYPERBALL, two γ-ray transitions from the 6.6MeV excited 12- state to both ground-states spin-doublet members 11- and 0- have been observed. The measured ground-state doublet spacing is 26.4 ± 1.6(stat) ± 0.5(syst) keV. Thus a small but nonzero strength of the tensor interaction between a A and a nucleon is deduced to be T = + 0.03 MeV. The excitation energy of the 12- state is also determined to be 6561.7 ± 1.1(stat) ± 1.7(syst) keV.
