计算了Na、K、Rb和Cs的主系振子强度和基态光电离截面。对每个原子的光电子极化程度也进行了预测。所有的计算都考虑了核-极化对偶极跃迁矩的修正，价p-电子轨道的自旋轨道微扰也包括在Rb和Cs振子强度和所有光致电离截面的计算中。将结果与最近的测量结果进行了比较。
Principal-series oscillator strengths and ground-state photoionization cross sections are computed for sodium, potassium, rubidium, and cesium. The degree of polarization of the photoelectrons is also predicted for each atom. The core-polarization correction to the dipole transition moment is included in all of the calculations, and the spin-orbit perturbation of valence-p-electron orbitals is included in the calculations of the Rb and Cs oscillator strengths and of all the photoionization cross sections. The results are compared with recent measurements.
