| Outline of Final Research Achievements |
We aim at searching for the not-yet established dinutron in neutorn-rich nuclei. For this purpose, we have planned to measure the two neutron correlation in the decay of 26O, and completed building the high-granularity neutron detector array, called HIME. However, due to the recent situation of short supply of 48Ca, the 48Ca beam is currently not available. Hence, we are still waiting for the beam deliverly.
We have also studied the dineutron in two-neutron halo nuclei using the Coulomb breakup experiments at RIBF at RIKEN. We have successfully obtained the electric dipole strength spectra for 6He and 19B. The extracted soft-E1 spectrum both showed the existence of dineutron structure of these nuclei. Such result may affect the structure of the surface of the neutron stars.
