摘要

High resolution γ spectroscopy of hypernuclei using Hyperball has revealed detailed level structure of several p-shell Λ hypernuclei and allowed us to extract the strengths of ΛN spin-dependent interactions. In the experiment BNL E930, we observed E2(3/2+,5/2+ → 1/2+) transitions in Λ9 Be and confirmed a small size of the Λ-spin-dependent spin-orbit force. Recently we took data for Λ16O and Λ15N in order to investigate the strength of the AN tensor force. In a preliminary analysis, we observed γ rays of Λ16O and Λ15N.
