We carried out an experiment to produce the neutron-rich hypernucleus 6ΛH via the (∏−, K+) reaction on 6Li 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 Λ binding energy of the hypernucleus, we also measured the 12C(∏+, K+)12ΛC, p(∏−, K+)Σ− and p(∏+, K+)Σ+ reactions.
The experiment was performed at the J-PARC Hadron Hall K1.8 beam line
in December 2012 and January 2013. The overall collected data sample
corresponds to an integrated beam intensity of 1.65 × 1012 pions.
