对于发生在同一个原子核中的、从一种高有序激发模式向着另一种低有序激发模式演化的机理和物理图像,提出了一种新的理解:被布居到高角动量态的高有序激发核,以E2跃迁方式先行退耦到yrast带,再退耦到共存区时释放了结构能,诱发价核子对耦合强度改变,重新组合出低有序的激发模式基准态,实现了基准态结构的过渡.从微观上看,这是一种既温和而又平稳的转变.并以76Sr核为例作了深入阐述.
A new understanding of the mechanisms and physical images that evolve from one highly ordered excitation mode to another in the same atomic nucleus has been proposed: The excitation nuclei are first decoupled to the yrast zone by means of the E2 transition and then released to the coexistence zone. The structure energy is released, the coupling strength of the induced nuclei is changed, and the low order excitation mode reference state is recombined to achieve the reference This is a mild and smooth transition from the microscopic point of view, with the 76Sr core as an example.
