The goal of the experiment is the precise spectroscopy of hypernuclei in wide mass region. We have constructed a new high resolution electron spectrometer "HES" dedicated to (e,e' K+) hypernuclear study in Japan and it was shipped to JLab in February,2008. We will discuss about the physics of the (e,e' K+) hypernuclear study at JLab and report the current preparation status of the third generatrion experiment.展开更多

The data have been compared with SAID and MAID model calculations. π0 photoproduction on the deuteron shows a strong suppression of the 2nd resonance which is clearly seen in the γp→π0p reaction.展开更多
