- 論文の詳細を見る
A molecular model developed for resonances observed in medium light heavy-ion collisions is described. At high spins in ^<28>Si + ^<28>Si (oblate-oblate system), a stable dinuclear configuration is found to be equator-equator touching one. The normal modes around the equilibrium are investigated. These modes are expected to be the origin of a large number of resonances observed. Furthermore, due to the axially asymmetric shape of the stable configuration of ^<28>Si + ^<28>Si, the system rotates preferentially around the axis with the largest moment of inertia, which gives rise to wobbling motion (K-mixing). Energy spectra for the normal modes and for the extended model including the wobbling motion are given.
