用蒙特卡罗壳层模型（MCSM）计算了pfg 9d5壳层中Cr和Ni的同位素组成.在MCSM中，波函数被表示为角动量和宇称投影变形斯莱特行列式（MCSM基）的线性组合，并且我们可以在大的模型空间（如PFG 9 d 5壳）中计算本征态。我们利用非投影MCSM基的形变来研究原子核的内禀形状。给出了Cr、Ni同位素的计算结果和68Ni的能级图，讨论了Cr、Ni同位素中N= 40的磁性强度和68Ni的形状共存。
We study Cr and Ni isotopes by Monte Carlo shell model (MCSM) calculations in a pfg 9 d 5 shell. In the MCSM, the wave function is represented as a linear combination of angular-momentum-and parity-projected deformed Slater determinants (MCSM bases), and we can calculate eigenstates in a large model space such as the pfg 9 d 5 shell. We study the intrinsic shape of nuclei by using deformations of the unprojected MCSM bases. We show calculated results of Cr and Ni isotopes and a level scheme of 68 Ni, and discuss the strength of the magicity of N= 40 in Cr and Ni isotopes and shape coexistence in 68 Ni.
