【 摘 要 】

Electromagnetic transitions from deformed structures based on α configurations or on heavier clusters are discussed, drawing the link between multiparticle-multihole excited bands and cluster structures. Enhanced E2 and E1 transitions are reviewed in the light nuclei,8Be,10Be,12C,16O,18O and heavier ones like212Po. Connections between cluster structures and superdeformed configurations in36Ar and40Ca are discussed. What the cluster states based on heavier substructures like12C and16O are concerned, recent results on the resonant radiative capture reaction12C(16O,γ)28Si are presented, in particular the strong decay mode involving the feeding of low-lying28Si 1+and 2+T=1 states by enhanced M1 isovector transitions.
