Abstract
Emulsion Cloud Chamber(ECC) with 65kg iron target was exposed to the neutrino beam at J-PARC neutrino beamline in 2016. It is capable of detecting slow protons as low as 200 MeV/c. In this document, we use the data set corresponding to 0.40$\times$10$^{20}$ protons on target. A total of 194 neutrino-iron charged current interactions were successfully reconstructed. Emission angles and momenta of muon and protons in the final state of each event were measured and compared with those of a Monte Carlo simulation. This is the first measurement using the iron ECC in this energy region.
