Abstract

The present status of hypernuclear γ-ray spectroscopy with Hyperball is summarized. We observed two γ transitions of Λ16O(1- → 1-, 0-) and obtained the strength of the ΛN tensor force. In 10B(K- π- γ) data, we did not observe the spin-flip M1 transition of Λ10B(2- → 1-), but γ rays from hyperfragments such as Λ7Li(7/2+ → 5/2+) and Λ9Be(3/2+ → 1/2+) were observed. In 11B(π+, K+ γ) data, we observed six γ transitions of Λ11B. We also attempted an inclusive γ-ray measurement with a stopped K- beam.
