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.
