A series of hypernuclear gamma-ray spectroscopy experiments using a germanium detector array, Hyperball, have accumulated precise data on various p-shell Lambda hypernuclei. We observed "hypernuclear fine structure" in various hypernuclei and extracted the strengths of the spin-dependent parts of the Lambda-N interaction. The obtained strengths allow us to reproduce structure of Lambda...

Many high-resolution γ-ray spectroscopy experiments have been carried out for s-shell and p-shell Λ-hypernuclei in order to understand the nature of Λ-nucleon interaction in nuclear medium and the impurity effect of a Λ on nuclear structure. The J-PARC facility will provide an opportunity to perform hypernuclear γ-ray spectroscopy study with high precision by improving the quality of the...

At the J-PARC facility, several light hypernuclei will be studied via gamma-ray spectroscopy at the K1.8 beam line as a Day-1 experiment (E13). We will study 4{$lambda}He to solve puzzle of charge symmetry breaking and 19{$lambda}F to study spin-dependent {$lambda}N interaction in sd-shell at the initial stage of E13. Gamma rays from the hypernuclei are detected by a new germanium(Ge) detector...

The HypHI project aims to study relativistic hypernuclei in-flight by means of induced reactions of heavy ion projectiles impinged on a fixed target. The first experiment, so called Phase 0, has been performed at GSI with 6LI projectiles at 2 A GeV on a carbontarget, which has demonstrated the feasibility of the experimental principle of the project. Details of the experiment and first results...
