| Outline of Final Research Achievements |
New hypernuclear systems with strangeness -2 were searched for with the (K-, K+) reaction. From the data analysis of already existing spectrometer with the energy resolution of 6 MeV, we succeeded to observe a Xi bound state. It is consistent with the previous measurement at BNL with the energy resolution of 14 MeV. In addition, we also observed an experimental signature of possible excitation of an excited level of a double-lambda hypernucleus. It was observed because of the great improvement of the energy resolution. We have succeeded to develop an active fiber target system, and are waiting for a new measurement with 2 MeV resolution.
