Observation of Coulomb-assisted nuclear bound state of -N system
S. H. Hayakawa, K. Agari, J. K. Ahn +95
In an emulsion-counter hybrid experiment performed at J-PARC, a absorption event was observed which decayed into twin single- 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- hypernucleus, , was observed by the J-PARC E07 collaboration in nuclear emulsions tagged by the reaction. This event was interprete…
First Determination of Level Structure of an -Shell Hypernucleus,
S. B. Yang, J. K. Ahn, Y. Akazawa +45
We report on the first observation of rays emitted from an -shell hypernucleus, . The energy spacing between the ground state doublet, and …
Search for Tetraneutron by Pion Double Charge Exchange Reaction at J-PARC
Hiroyuki Fujioka, Tomokazu Fukuda, Toru Harada +6
Tetraneutron () has come back in the limelight, because of recent observation of a candidate resonant state at RIBF. We propose to investigate the pion double charge exchange…
