用投影壳模型(PSM)对98-102Sr和100-104Zr核进行了研究。通过再现Yrast谱和电磁性质，验证了基态波函数的可靠性。找出了N=60时突然大变形的发生机制。这项研究工作统一了球壳模型和平均场理论对N=60时形变开始的两种不同的或相互冲突的早期解释。
The projected shell model (PSM) study of 98-102 Sr and 100-104 Zr nuclei is carried out. The reliability of the ground-state wave function is checked by reproducing yrast spectra and electromagnetic properties. The mechanism for the onset of sudden and large deformation at N = 60 is worked out. The present piece of research work has unified the two different, or conflicting, early explanations for the onset of deformation at N = 60 by the spherical shell model and mean-field theory.
