The reaction is an important elementary process to produce from a proton target and is a key for a scattering experiment where the momentum of should be tagged from the missing momentum of the reaction. However, the spectroscopy method has not been established yet due to the difficulty of the detection. Therefore, we have proposed a new detection method where and from the decay are measured by a forward magnetic spectrometer and a detector cluster surrounding the target, respectively. The feasibility of the detection method was confirmed by analyzing the J-PARC E40 data taken with such a detector system. In the analysis, 's were successfully identified in the missing mass spectrum of the reaction.

J-PARC E40 aims to measure the differential cross sections of the elastic scatterings and the conversion. A clear peak of was observed in a missing mass spectrum of the reaction and recoil protons from the elastic scattering were successfully observed in the data taken in the summer 2018. The rest of data taking is coming in the spring 2019.
