Times Cited Count：14 Percentile：65.44(Physics, Multidisciplinary)Level structure of the C hypernucleus was precisely determined by means of -ray spectroscopy. We identified four -ray transitions via the 
C
reaction using a germanium detector array, Hyperball2. The spacing of the ground-state doublet 
was measured to be 
(stat)
(syst)keV from the direct 
transition. Excitation energies of the 
and 
states were measured to be 
, keV and 
, keV, respectively. The obtained level energies provide definitive references for the reaction spectroscopy of 
hypernuclei.

A high-resolution beam imaging system was newly developed for pulsed muon beams in J-PARC MUSE using a plastic scintillator, a gated image intensifier, and a cooled CCD camera. The system was optimized for observation of 4 MeV muon beams and designed so as to be used with an existing muSR spectrometer in the D1 area, J-PARC MUSE. High-resolution beam profiles were obtained for a surface muon beam after exposure to the beam for several tens of seconds. A contribution from decay positrons was significantly suppressed by gating of the image ntensifier. Details of test experiments (negative muon beam profiles in the D2 area, 3D beam imaging, noise reduction, etc.) were presented.
