摘要

本文采用准粒子随机相近似(QRPA)方法系统地研究了偶偶124-134Xe同位素的低洼偶极态。在所有被研究的氙同位素中，电偶极子和磁偶极子的响应都得到了明确的预测。计算主要预测了剪子模式，而弱变形的132,134xe的强度与中度变形的124-130Xe同位素相比较小，其中电偶极子激发也有自己的贡献。所得结果与现有实验数据吻合较好。由于不可能通过实验来确定偶极态的宇称，因此我们研究了电偶极和磁偶极激发在形成谱中的作用。在将所得结果与实验推导的结果进行比较后，确定了几个观测到的自旋未知和宇称未知激发的性质。

Dipole responses in γ−soft 124-134Xe in the spectroscopic energy region

This study aimed to systematically investigate the low-lying dipole states of even-even 124-134Xe isotopes using the quasi-particle random phase approximation (QRPA) method. Where in all the studied xenon isotopes, electric and magnetic dipole responses were clearly predicted. The calculations predict mainly a scissors mode, while the strength of weakly deformed 132, 134Xe was small compared to moderately deformed 124-130Xe isotopes, where electric dipole excitations make their own contributions as well. The obtained results are consistent with the available experimental data. Since it was not possible to experimentally determine the parity of dipole states here trougth comparison our results with experiment, we investigated the role of electric and magnetic dipole excitations in forming the spectrum. After comparing the obtained results with the experimentally derived ones, the natures of several observed spin- and parity-unknown excitations were determined.
