| Outline of Final Research Achievements |
Purpose of this work is to investigate a charge symmetry breaking between the 4-Lambda-H and the 4-Lambda-He hypernuclei via the gamma-ray spectroscopy. To observe a 4-Lambda-He gamma-ray, J-PARC E13 was planned and will be held in 2015.I prepared the whole system of E13, in particular, wide acceptance pi-spectrometer,SksMinus.On the other hand, To observe a 4-Lambda-H gamma-ray, pi0 spectrometer to tag the (K-,pi0) reaction is needed.So that, in this work, pi0 spectrometer was developed. In particular, lead-glass calorimeter as a EM shower counter system was studied.
