论文摘要
首次使用显微镜投射的壳模型研究了两个新观察到的频带,这是首次研究了130BA的两夸西拉颗粒构型。实验能光谱和可用的电磁过渡概率得到了很好的再现。较高带的摇摆特征通过k图和方位角图揭示了角动量投射的波形。这提供了基于均匀核中的两数粒子构型的摇摆运动的第一个强大显着证据。
Two newly observed bands built on a two-quasiparticle configuration in 130Ba have been investigated for the first time with the microscopic projected shell model. The experimental energy spectra and the available electromagnetic transition probabilities are well reproduced. The wobbling character of the higher band is revealed by the angular momentum projected wavefunctions via the K plot and the azimuthal plot. This provides the first strong microscopic evidence for wobbling motion based on a two-quasiparticle configuration in even-even nuclei.
