摘要
We carried out an experiment to produce the neutron-rich hypernucleus H-6(Lambda) via the (pi(-), K+) reaction on Li-6 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 Lambda binding energy of the hypernucleus, we also measured the C-12(pi(+), K+)(12)(Lambda)12, p(pi(-), K+)Sigma(-) and p(pi(+), K+)Sigma(+) 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 x 10(12) pions.
