Abstract: A γ-ray spectroscopy experiment via the (K^−, π^−) reaction (J-PARC E13-1st) will be performed at the J-PARC Hadron Experimental Facility using a newly developed Ge detector array, Hyperball-J. Spin-dependent ΛN interactions will be studied through the precise measurement of the structure of hypernuclei, \(_{\Lambda }^{4}\text{He}\) and \(_{\Lambda }^{19}\text{F}\). In May 2013, commissioning of whole detector system was carried out and calibration data were taken. In particular, production cross sections of Σ^+ and \(_{\Lambda }^{12}\text{C}\) via the (K^−, π^−) reaction on the CH_2 target for = 1.5 and 1.8 GeV/c were obtained.
