Abstract

A recent experimental progress of strangeness nuclear physics is reviewed from viewpoint of hyperon-nucleon (YN) and hyperon-hyperon (YY) interactions. Detailed level structure of Λ hypernuclei has been studied by γ-ray spectroscopy technique using a germanium detector array as well as an NaI counter array, which determined the strengths of the ΛN spin-spin and spin-orbit interactions. In the emulsion-counter hybrid experiment, a double Λ hypernucleus _ΛΛ ⁶ He was observed and the strength of the ΛΛ interaction was unambiguously derived. As for the ∑N interaction, a recent ²⁸Si(π^-, K⁺) spectrum suggests a strongly repulsive ∑-nucleus potential, while the spin-orbit force of ∑ is being studied by a ∑p scattering experiment.
