Outline Activities
Study of nuclear reaction using heavy-ion beams
I study nuclear physics based on the reaction using heavy-ion beams. The experiments are performed mainly at the RIKEN RI beam factory (Saitama, Japan) and QST HIMAC (Chiba, Japan). The main work is to elucidate the nuclear structures of exotic unstable nuclei by extracting the radius of the atomic nucleus via reaction-probability measurements.

The obtained barrier distribution is well explained by the coupled-channels calculation, indicating a significant effect of the rotational excitation of deformed Cm-248. From the measured average Coulomb barrier height and deformation parameters of Cm-248, the side-collision energy leading to a compact configuration of colliding nuclei was obtained. The relation between the side collision energy and the excitation function of the evaporation-residue cross sections in the Ca-48+(CM)-C-248 system was evaluated as a reference for the V-51+ Cm-248 case. The optimal reaction energy to synthesize a new element 119 at the V-51+ Cm-248 fusion reaction (3n and 4n channels) was estimated with an aid of these experimental data..
