用推广的玻尔哈密顿量方法计算氪同位素的结构

Structure of Krypton Isotopes using the Generalised Bohr Hamiltonian Method

David Muir, Leszek Próchniak, Alessandro Pastore, Jacek Dobaczewski

摘要:

我们研究了氪的偶偶同位素的激发光谱的性质,使用广义玻尔哈密顿量与三个不同的Skyrme泛函。特别是,我们研究了低的$2^{+}_{1}$和$4^{+}_{1}$状态和它们相关的电磁跃迁的演变。该模型很好地再现了除了${}^{88}$ Kr之外的能量趋势,这里使用的相互作用都不能抓住能谱的突然变化。此外,我们探索中子缺乏区域${}^{72-76}$ Kr,这是一个建议的形状共存的区域。我们观察到,该模型可以非常好地再现${}^{72}$ Kr的实验光谱结构。

英文摘要:

We investigate the properties of the excited spectra of the even-even isotopes of krypton using a Generalised Bohr Hamiltonian with three different Skyrme functionals. In particular, we investigate the evolution of the low-lying $2^{+}_{1}$ and $4^{+}_{1}$ states and their associated electromagnetic transitions. The model reproduces quite nicely the energy trends apart from ${}^{88}$Kr, where none of the interactions used here are able to grasp a sudden change in the energy spectrum. Additionally, we explore the neutron deficient region ${}^{72-76}$Kr which is a proposed region for shape coexistence. We observe that the model can reproduce the structure of the experimental spectrum of ${}^{72}$Kr exceedingly well.
