190 W中旋转驱动的长扁相变:投影壳模型研究

Rotation-driven prolate-to-oblate shape phase transition in 190W: A projected shell model study

Yang Sun, Philip M. Walker, Fu-Rong Xu, Yu-Xin Liu

摘要:

应用投影壳模型,超出了通常的平均场近似,证明了在190 W时发生形状相变。在高j,i_{13/2}轨道中的中子旋转排列驱动系统的yrast序列,在角动量为10 $\hbar$时突然从扁长变为扁球形。我们提出了可观测的测试图片。

英文摘要:

A shape phase transition is demonstrated to occur in 190W by applying the Projected Shell Model, which goes beyond the usual mean-field approximation. Rotation alignment of neutrons in the high-j, i_{13/2} orbital drives the yrast sequence of the system, changing suddenly from prolate to oblate shape at angular momentum 10$\hbar$. We propose observables to test the picture.
