论文摘要
通过将准粒子耦合到均匀的核心通过核心 - Quasiparticle耦合模型来研究奇数核的三轴性。考虑了软和刚性三轴核心。 “软核”由带有旋转振动运动的集体模型描述，而“刚性核心”由三轴转子模型描述，这是一个只有旋转运动的集体模型的限制情况。我们表明，奇数准颗粒的存在会改变核心的集体四极动力学，以显示更多“刚性”。
The triaxiality of odd-mass nuclei is investigated by coupling a quasiparticle to an even-even core through the core-quasiparticle coupling model. Both soft and rigid triaxial cores are considered. The "soft core" is described by the collective model with rotation-vibrational motion, while the "rigid core" is described by the triaxial rotor model, which is a limiting case of the collective model with only rotational motion. We show that the presence of the odd quasiparticle modifies the collective quadrupole dynamics of the core to appear more "rigid".
