球形核或基态弱形变的核的超稳态被描述为在核表面上运动的四极波，我们称之为“潮汐波”。本文用推转模型从微观上计算了Z= 44，46，48和N= 56，58，…，66的核素Yrast态的能量和E2跃迁几率。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。
The yrast states of nuclei that are spherical or weakly deformed in their ground states are described as quadrupole waves running over the nuclear surface, which we call "tidal waves". The energies and E2 transition probabilities of the yrast states in nuclides with Z= 44, 46, 48 and N= 56, 58,…, 66 are calculated by means of the cranking model in a microscopic way. The nonlinear response of the nucleonic orbitals results in a strong coupling between shape and single particle degrees of freedom.
