Hypernuclear gamma-ray spectroscopy: summary and future prospect

Abstract

The present status and prospects of hypernuclear γ-ray spectroscopy are summarized. In particular, 4-body hypernuclear γ-ray spectroscopy, the recent result of 4ΛHe and the future plan of 4ΛH and charge symmetry breaking in the ΛN interaction are presented. In addition, future plans to measure the Λ-spin-flip B(M1) values of 7Λ(3/2+ → 1/2+) and 12ΛC(2− → 1−) transitions are introduced. They aim to study the g-factor of Λ in the nuclear medium.
