论文摘要
在超出平均野外框架中研究了$ n = 42 $，44和46的KR同位素的yrast线，并考虑了prate-obleder的共存和Quasiparticle对准。证明具有高$ j $和低$ j $的准粒子轨道，被证明是造成$^{82} $ kr中观察到的急转弯，通过将yrast的形状从珍贵的形状驱动到底漆。这表明在研究沿yrast线的形状演化时，可能不会忽略准粒子比对。
The yrast lines in Kr isotopes with $N=42$, 44, and 46 are investigated in a beyond mean field framework with both prolate-oblate coexistence and quasiparticle alignment taken into account. Quasiparticle orbitals with high-$j$ and low-$Ω$ on the oblate side are shown to be responsible for the sharp backbending observed in $^{82}$Kr, by driving the yrast shape from prolate to oblate. This suggests that quasiparticle alignment may not be neglected in the investigation of the shape evolution along the yrast line.
