| Outline of Final Research Achievements |
The subject of this research is a study of new nuclei 'Lambda hypernuclei' for which a Lambda hyperon, one of baryon with the strangeness degree of freedom, is embedded in nuclei. The double charge-exchange reaction is employed to create and study neutron-rich Lambda hypernuclei. One of difficulties in the measurement of the double charge-exchange reaction is the tiny reaction cross section. To override the difficulty, high-intensity hadron beams are used, and detectors are developed for the high beam rate environment. An experiment to search for the neutron-rich Lambda hypernucleus 6(Lambda)H close to the neutron drip-line was performed at the J-PARC 50GeV Proton Synchrotoron Accelerator facility.
