¹⁶ O + ¹⁶ O nature of the superdeformed band of ³² S and the evolution of the molecular structure

الأصل · EN

The relation between the superdeformed band of ³² S and ¹⁶ O + ¹⁶ O molecular bands is studied by the deformed-base antisymmetrized molecular dynamics with the Gogny D1S force. It is found that the obtained superdeformed band members of ³² S have considerable amount of the ¹⁶ O + ¹⁶ O component. Above the superdeformed band, we have obtained two excited rotational bands which have more prominent character of the ¹⁶ O + ¹⁶ O molecular band. These three rotational bands are regarded as a series of ¹⁶ O + ¹⁶ O molecular bands which were predicted by using the unique ¹⁶ O -¹⁶ O optical potentil. As the excitation energy and principal quantum number of the relative motion increase, the ¹⁶ O + ¹⁶ O cluster structure becomes more prominent but at the same time, the band members are fragmented into several states.
