J-PARC E10 and E22 Experiments

General

We aim to perform experiments with the K1.8 beam line of the 50 GeV proton-synchrotron facility at J-PARC. The high intensity pion beams by the slow beam extraction will be used. Our subjects are a copious production of the neutron-rich hypernuclei by the double-charge exchange (DCX) reactions (E10) and a detail study on the non-mesonic weak decay in the A=4 hypernuclei (E22).
