Description
We performed a γ-ray spectroscopy experiment of Λ16O using Hyperball for the purpose of determining the strength of the ΛN tensor force. We detected two γ rays of Λ16O corresponding to the transitions from the 6.5 MeV excited state (12-) to the ground state doublet (11-, 0-). The energies of the γ rays are 6534.1 ± 1.5 keV and 6560.2 ± 1.3 keV and the energy spacing is 26.1 ± 2.0 keV. From their yield ratio 0.66 ± 0.11 (N(6534)/N(6560)), the order of the states (1-, 0-) is determined. The result gives a small value for the ΛN tensor force strength. (author)
