Outline of Final Research Achievements

Dynamical studies on the specification of the form of unbound nuclei (nucleon many-body states) in reaction observables and their decay mode have been carried out. Some main results are 1) discovery of the peculiar shape of the second excited state of 22C in the breakup energy spectrum (cf. the Fano effect), 2) specification of the decay mode of the 2+ state of 6He, and 3) verification of the di-neutron correlation in 6He through the formation cross section of 5He.
