Precise determination of $_{Λ}^{12}$ C level structure by $γ$ -ray spectroscopy

K. Hosomi, T. Ma, S. Ajimura +30

Level structure of the $_{Λ}^{12}$ C hypernucleus was precisely determined by means of $γ$ -ray spectroscopy. We identified four $γ$ -ray transitions via the $^{12}$ C $(π^{+}, K^{+} γ)$ re…

Observation of the " $K^{-} pp$ "-like structure in the $d (π^{+}, K^{+})$ reaction at 1.69 GeV/ $c$

Yudai Ichikawa, Tomofumi Nagae, Hiroyuki Fujioka +41

We have observed a " $K^{-} pp$ "-like structure in the $d (π^{+}, K^{+})$ reaction at 1.69 GeV/ $c$ . In this reaction $Λ (1405)$ hyperon resonance is expected to be produced as a doorway to fo…

Production of Neutron-Rich Lambda Hypernuclei at J-PARC

A. Sakaguchi, S. Ajimura, H. Bhang +16

We discuss the usefulness of the double charge-exchange reactions (DCX) for the production of the neutron-rich Lambda-hypernuclei. We believe the (pi-,K+) reaction is one of the mo…

Gamma-Ray Spectroscopy in Lambda Hypernuclei

H. Tamura

The present status of hypernuclear gamma-ray spectroscopy with Hyperball is summarized. We observed two gamma transitions of 16-Lambda-O(1- -> 1-,0-) and obtained the strength of t…
