| Outline of Final Research Achievements |
A goal of this research was measurements of the hypernuclear weak decay. The investigation would proceed with hypernuclear studies if we measure hyper-hydrogen nuclei, which is difficult to generate with the standard reaction e.g, the (pi, K) or the (K, pi) reactions.
The investigation tried to generate hyper-hydrogen nuclei with a new reaction method (γ, K+) reaction. We successfully developed a new TOF counter for a Kaon identification and a high time resolution detector for measure decay particles. Those detectors are essential detectors to expand hypernuclear experiments with the photon beams.
