Outline of Final Research Achievements

An active target system with a micro pixel chamber was developed and a performance test was carried out using an accelerated beam. Three-dimensional trajectories of incident, scattered and recoil particles in the 4He + 4He elasctic scattering were successfully measured. The first measurement using a radioactive beam will be done in FY2015 to clarify cluster correlations in neutron-rich nuclei.
