Abstract

We performed an experiment to measure γ rays of hyperfragments produced by stopped K- reactions on light (A ≤ 12) targets (KEK-PS E509). We clearly observed an E2 transition (5/2+ → 1/2+) in Λ7Li with 10B, and 11B and 12C targets and obtained the γ-ray intensity to be (7.5 ± 1.6) × 10-4 per stopped K- for 10B target. In addition, a candidate for a new hypernuclear γ ray was observed. These results show that this method is quite suitable for the systematic study of hypernuclei.
