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
