论文摘要
基于单个粒子能量通过标准协变量功能理论计算，建议对n = 90，z = 64区域形状共存的性质的微观解释。建议在n = 90区域的形状共存是由质子引起的，质子会在n = 112 3维的各向同性谐波振荡器（3D-HO）上产生中子颗粒孔（p-h）兴奋并导致X（5）临界点对称性描述的从球形到变形核的形状/相变。在n = 60，z = 40区域中也看到了类似的效果，其中发生了n = 70 3d-ho魔术数的p-h激发，这表明了1H11/2入侵者轨道占用的开始。
A microscopic explanation of the nature of shape coexistence in the N=90, Z=64 region is suggested, based on calculations of single particle energies through standard covariant density functional theory. It is suggested that shape coexistence in the N=90 region is caused by the protons, which create neutron particle-hole (p-h) excitations across the N=112 3-dimensional isotropic harmonic oscillator (3D-HO) magic number, signaling the start of the occupation of the 1i13/2 intruder orbital, which triggers stronger proton-neutron interaction, causing the onset of the deformation and resulting in the shape/phase transition from spherical to deformed nuclei described by the X(5) critical point symmetry. A similar effect is seen in the N=60, Z=40 region, in which p-h excitations across the N=70 3D-HO magic number occur, signaling the start of the occupation of the 1h11/2 intruder orbital.
