应用投影壳模型证明了在190w发生的形状相变超出了通常的平均场近似。中子在高j， 13/2轨道上的旋转排列驱动了系统的快速序列，在角动量为10 ^时突然从长形变为扁形。我们提出了可观测物来检验这一图景。
A shape phase transition is demonstrated to occur in190W by applying the projected shell model, which goes beyond the usual mean-field approximation. Rotation alignment of neutrons in the high-j, i13/2orbital drives the yrast sequence of the system, changing suddenly from prolate to oblate shape at angular momentum 10ℏ. We propose observables to test the picture.
