We have collected the first physics data of an experimental search for the simplest kaonic nuclear bound state, “ K − pp”, by the 3He( K − n) reaction at J-PARC. We confirmed that our spectrometer system works as designed and observed clear peak structure composed of the quasi-elastic K − “ n ” → K − n and the charge-exchange K − “ p ” → ¯ K 0 n reactions in the forward neutron spectrum.
