Abstract：
In a 16ΛO γ-ray spectroscopy experiment with HYPERBALL, two γ-ray transitions from the 6.6MeV excited 1－2 state to both ground-states spin-doublet members 1－1 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 Λ and a nucleon is deduced to be T=+0.03MeV. The excitation energy of the 1－2 state is also determined to be 6561.7 ± 1.1(stat) ± 1.7(syst) keV.
