过渡核中潮汐波作为Yrast态
Tidal waves as yrast states in transitional nuclei
摘要：
过渡核的超稳态被描述为四极波，我们称之为潮汐波。与通过以近似恒定的变形增加角速度来产生角动量的转子相反，潮汐波通过以近似恒定的角速度增加变形来产生角动量。利用推转模型，从微观角度计算了潮波的性质。计算了$Z$ = 44，46，48和$N=56, 58, ..., 66$的过渡核素的yrast态的能量和E2跃迁几率，详细地再现了实验结果.核子轨道的非线性响应导致形状和单粒子自由度之间的强耦合。
英文摘要：
The yrast states of transitional nuclei are described as quadrupole waves running over the nuclear surface, which we call tidal waves. In contrast to a rotor, which generates angular momentum by increasing the angular velocity at approximately constant deformation, a tidal wave generates angular momentum by increasing the deformation at approximately constant angular velocity. The properties of the tidal waves are calculated by means of the cranking model in a microscopic way. The calculated energies and E2 transition probabilities of the yrast states in the transitional nuclides with $Z$= 44, 46, 48 and $N=56, 58, ..., 66$ reproduce the experiment in detail. The nonlinear response of the nucleonic orbitals results in a strong coupling between shape and single particle degrees of freedom.
