摘要

The α inelastic scatterings and the (α,t) reaction on exotic nuclei at 50-60 A MeV are discussed. A new multipole decomposition analysis taking into account the angular correlation of decaying process originated from the alignments of the residual nucleus is applied for a study of cluster states in ~(12)Be. The proton transfer reaction on the ~(12)Be nucleus populates a possible proton single-particle state bound by a deformed core in the ~(13)B nucleus of which ground state is spherical. For a new spectroscopy of nuclei using intense RI beams at RIBF, we started the SHARAQ project where a high-resolution SHARAQ spectrometer is being constructed together with a high-resolution secondary beam line. Physics motivation and the specification of the spectrometer are presented.
