从头算非核组态相互作用计算中转动带的出现

Emergence of rotational bands in ab initio no-core configuration interaction calculations

摘要:

在p-壳层原子核的从头算无核组态相互作用(NCCI)计算中,已经观察到转动带的出现,这可以从激发能、电磁矩和电磁跃迁的转动模式中得到证实。我们研究了Be同位素中原子核转动的从头算现象,以9 Be为例,利用基外推方法得到转动带参数的从头算预测,并与实验进行了比较.我们发现强大的签名旋转运动,再现实验观察到的频带的定性和定量特征。

英文摘要:

Rotational bands have been observed to emerge in ab initio no-core configuration interaction (NCCI) calculations for p-shell nuclei, as evidenced by rotational patterns for excitation energies, electromagnetic moments, and electromagnetic transitions. We investigate the ab initio emergence of nuclear rotation in the Be isotopes, focusing on 9Be for illustration, and make use of basis extrapolation methods to obtain ab initio predictions of rotational band parameters for comparison with experiment. We find robust signatures for rotational motion, which reproduce both qualitative and quantitative features of the experimentally observed bands.
