【 摘 要 】

We have carried out an experiment to produce the neutron-rich hypernucleus6ΛH by the (π-,K+) reaction on6Li target at the pion beam momentum of 1.2 GeV/c (J-PARC E10). In order to calibrate the scale of the missing-mass or of the A binding energy of the hypernucleus, we also measured the12C(π+,K+)12ΛC, p(π+K+)Σ-and p(π+,K +)E+ reactions. The experiment was performed at the K1.8 beam line of J-PARC Hadron Experimental Facility. The overall collected data sample corresponds to an integrated beam intensity of 1.4 × 1012pions.
