Abstract
Studies of resonances in heavier systems are reviewed. A molecular model developed for heavy-ion resonances is described briefly. At high spins, stable dinuclear configurations are obtained as an equator-equator touching one for 28Si + 28Si (oblate-oblate system) and a pole-to-pole one for 24Mg + 24Mg (prolate-prolate system), respectively. Normal modes have been investigated around those equilibria. Those modes are expected to be the origin of a large number of the resonances observed. Furthermore, it is clarified that those different-type of equilibria give rise to their own characteristic rotational excitations. The importance of recent experimental data measured in Strasbourg, for both the 28Si+28Si and the 24Mg +24Mg systems are stressed. Analyses of physical quantities are made and compared with those data.
