论文摘要
已经计算出磁性超细结构常数，这些磁性高磷酸原子中的低凹水平考虑了Bohr-Weisskopf（BW）和Breit- rosenthal（BR）效应。根据我们的结果，$ 4p_ {1/2} $ k〜I状态在当前理论不确定性的级别上都没有BR和BW校正。使用此发现以及$ a（4p_ {1/2}）$常数的测量值，我们校正了几个短寿命的钾同位素的核磁矩。 BW校正表示为原子和核因子的产物。我们计算了K I基态的原子因子，这使我们能够从实验数据中提取钾$ i^π= 3/2^+$同位素的核因子。通过这种方式，已经阐明了这些同位素中核因素计算的单粒子核模型的应用范围。
The magnetic hyperfine structure constants have been calculated for low-lying levels in neutral potassium atom taking into account the Bohr--Weisskopf (BW) and Breit--Rosenthal (BR) effects. According to our results the $4p_{1/2}$ state of K~I is free from both BR and BW corrections on the level of the current theoretical uncertainties. Using this finding and the measured values of the $A(4p_{1/2})$ constants, we corrected the nuclear magnetic moments for several short-lived potassium isotopes. The BW correction is represented as a product of atomic and nuclear factors. We calculated the atomic factor for the ground state of K I, which allowed us to extract nuclear factors for potassium $I^π= 3/2^+$ isotopes from the experimental data. In this way the application range of the single-particle nuclear model for nuclear-factor calculation in these isotopes has been clarified.
