| Research Abstract |
Process of exothermic charge exchange producing neutron-rich nuclei and multi-neutron system was investigated for understanding dynamics of multi-neutron system. Tracking detectors for high-resolution magnetic spectrometer(SHARAQ) and beam-line were developed as well as an intelligent detection system for two coincident alpha particles. Populations of highly excited states via an exothermic charge exchange reaction and of light neutron-rich nuclei via double charge exchange reaction were demonstrated, which is a basis for the experiment of tetra-neutron system scheduled in early 2012.
