论文摘要
我们使用具有三种不同Skyrme功能的广义Bohr Hamiltonian研究了K Krypton偶数同位素的激发光谱的性能。特别是，我们调查了低洼$ 2^{+} _ {1} $和$ 4^{+} _ {1} $状态及其关联的电磁过渡的演变。该模型很好地重现了能量趋势以外的$ {}^{88} $ kr，这里使用的任何相互作用都无法掌握能量谱的突然变化。此外，我们探索中子缺陷区域$ {}^{72-76} $ kr，这是形状共存的建议区域。我们观察到该模型可以重现$ {}^{72} $ kr的实验光谱的结构。
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.
