Observation of Coulomb-assisted nuclear bound state of $Ξ^{-}$ - $^{14}$ N system

S. H. Hayakawa, K. Agari, J. K. Ahn +95

In an emulsion-counter hybrid experiment performed at J-PARC, a $Ξ^{-}$ absorption event was observed which decayed into twin single- $Λ$ hypernuclei. Kinematic calculations enabled a…

Observation of a Be double-Lambda hypernucleus in the J-PARC E07 experiment

H. Ekawa, K. Agari, J. K. Ahn +100

A double- $Λ$ hypernucleus, $_{ΛΛ} Be$ , was observed by the J-PARC E07 collaboration in nuclear emulsions tagged by the $(K^{-}, K^{+})$ reaction. This event was interprete…

First Determination of Level Structure of an $s d$ -Shell Hypernucleus, $_{Λ}^{19} F$

S. B. Yang, J. K. Ahn, Y. Akazawa +45

We report on the first observation of $γ$ rays emitted from an $s d$ -shell hypernucleus, $_{Λ}^{19} F$ . The energy spacing between the ground state doublet, $1/ 2^{+}$ and $3/ 2^{+}$ …

Observation of Spin-Dependent Charge Symmetry Breaking in $Λ N$ Interaction: Gamma-Ray Spectroscopy of $_{Λ}^{4}$ He

T. O. Yamamoto, M. Agnello, Y. Akazawa +51

The energy spacing between the ground-state spin doublet of $_{Λ}^{4}$ He(1 $^{+}$ ,0 $^{+}$ ) was determined to be $1406 \pm 2 \pm 2$ keV, by measuring $γ$ rays for the $1^{+} \to 0^{+}$ transitio…
