论文摘要
我们使用来自不同核模型的核电电荷分布来计算野生原子的场同位素变化。我们证明，将计算出的同位素转移与实验进行比较可以作为核理论的测试场。它还提供了一种提取核电荷分布参数以外的核电RMS半径以外的方法，例如四极变形的参数$β$。我们认为，以$δ\ langle r^2 \ rangle $在$^{252,254}之间对同位素测量的解释，当考虑到核变形时，应修改同位素。我们计算其他已知同位素的同位素偏移，并假设亚固定型同位素$^{286} $否 核模型的预测有很大差异。
We calculate field isotope shifts for nobelium atoms using nuclear charge distributions which come from different nuclear models. We demonstrate that comparing calculated isotope shifts with experiment can serve as a testing ground for nuclear theories. It also provides a way of extracting parameters of nuclear charge distribution beyond nuclear RMS radius, e.g. parameter of quadrupole deformation $β$. We argue that previous interpretation of the isotope measurements in terms of $δ\langle r^2 \rangle$ between $^{252,254}$No isotopes should be amended when nuclear deformation is taken into account. We calculate isotope shifts for other known isotopes and for hypothetically metastable isotope $^{286}$No for which the predictions of nuclear models differ substantially.
