$^{133}$ Ce中存在多手性双谱带的证据
Evidence for Multiple Chiral Doublet Bands in $^{133}$Ce
摘要:
在核$^{133}$ Ce中发现了两组不同的手性伴侣带。它们构成了一个多手性双峰(M $χ$ D),相对论平均场(RMF)计算预测的现象,并在实验上观察到这里的第一次。这些手征带的性质与基于约束三轴RMF理论和粒子转子模型相结合的计算结果吻合得很好。
英文摘要:
Two distinct sets of chiral-partner bands have been identified in the nucleus $^{133}$Ce. They constitute a multiple chiral doublet (M$χ$D), a phenomenon predicted by relativistic mean field (RMF) calculations and observed experimentally here for the first time. The properties of these chiral bands are in good agreement with results of calculations based on a combination of the constrained triaxial RMF theory and the particle-rotor model.
