• The exotic properties of very neutron-rich nuclei beyond N=20 in the island of inversion region have been observed on the basis of the high luminosity obtained at RIPS as well as the newly developed spectroscopic technique. The particle stability of ^31F and the particle instability of ^28O have indicated a stability jump manifested in the very neutron-rich fluorine isotopes. The energies of low excited states for ^34Mg were observed via the in-beam gamma spectroscopy with the RI beam fragmentation method, and the B(E2) value of ^34Mg was measured via the intermediate energy Coulomb excitation method, suggesting that ^34Mg has a larger deformation than ^32Mg. Spectroscopic methods developed at not only RIKEN, but also other RI beam facilities will be naturally applied in the RIKEN future program, called RI Beam Factory (RIBF) project. The RIBF project was proposed to further promote research fields by utilizing RI beams which are now being used at RIPS. At RIBF, the range of radioactive nuclei will be expanded up to U, to enforce the advantage of RI beams. According to the expansion of available beams toward heavier nuclei, studies on the nuclear structure of very neutron-rich nuclei at N=50 and 82 will be possible.
