富含中子的A ~ 100核是核物质中微观和宏观效应相互作用的最好例子之一。众所周知，在富含中子的Zr和Sr同位素中，在N= 60左右会发生快速的四极变形，这使得该区域成为实验和理论研究的活跃区域。早在20世纪60年代，约翰逊就研究了252Cf的轻裂变碎片的性质，并在A= 110[1]附近观察到一个大而恒定的变形岛。后来，在核图这一区域的质量测量表明，Rb、Sr、Y和Zr同位素的结合能在N= 60[2]时迅速增加。这种稳定的开始被解释为一种* * * * * * *的结果。真的吗
Neutron-rich, A∼ 100 nuclei are among the best examples of the interplay of microscopic and macroscopic effects in nuclear matter. A rapid onset of quadrupole deformation is known to occur at around N= 60 in the neutron-rich Zr and Sr isotopes, making this region an active area for both experimental and theoretical studies. Already in the 1960s, Johansson investigated properties of light fission fragments of 252Cf and observed an island of large, constant deformation around A= 110 [1]. Later, mass measurements in this region of the nuclear chart showed that the binding energy of Rb, Sr, Y and Zr isotopes rapidly increases at N= 60 [2]. This onset of stability has been interpreted as a consequence of a* clement@ ganil. fr
