具有量化不确定性的核振动的有效场论

Effective field theory for nuclear vibrations with quantified uncertainties

E. A. Coello Pérez, T. Papenbrock

摘要:

我们发展了一个原子核振动的有效场论。关键成分-四极自由度,旋转不变性,和周围的三声子水平的崩溃规模-从数据。EFT是为光谱和电磁矩和跃迁而开发的。我们采用贝叶斯统计的工具来量化理论上的不确定性。EFT在理论不确定度范围内一致地描述了$^{62}$ Ni、$^{98,100}$ Ru、$^{106,108}$ Pd、$^{110,112,114}$ Cd和$^{118,120,122}$ Te的光谱和电磁跃迁。这表明这些原子核可以被看作是非谐振子。

英文摘要:

We develop an effective field theory (EFT) for nuclear vibrations. The key ingredients - quadrupole degrees of freedom, rotational invariance, and a breakdown scale around the three-phonon level - are taken from data. The EFT is developed for spectra and electromagnetic moments and transitions. We employ tools from Bayesian statistics for the quantification of theoretical uncertainties. The EFT consistently describes spectra and electromagnetic transitions for $^{62}$Ni, $^{98,100}$Ru, $^{106,108}$Pd, $^{110,112,114}$Cd, and $^{118,120,122}$Te within the theoretical uncertainties. This suggests that these nuclei can be viewed as anharmonic vibrators.
