Halley等人最近提出的新方法，结合R矩阵和复坐标旋转方法计算近阈值共振支配谱，将其推广应用于电场和平行电场/磁场中的谱计算。以上的经典电离阈值的钠原子的斯塔克光谱得到的结果与实验结果和那些从以前的计算使用半经典方法是非常一致的。钠原子在相同的能量区域，但在平行的电场和磁场中获得的结果代表了第一次获得的任何非氢原子在这样的组合场以上的经典电离阈值。
The new method recently presented by Halley et al., combining R-matrix and complex coordinate rotation methods for the calculation of near-threshold resonance dominated spectra, is extended and applied to the calculation of spectra in electric and parallel electric/magnetic fields. Results obtained for the Stark spectra of the sodium atom above the classical ionization threshold are in excellent agreement with experimental findings and those from a previous calculation using a semiclassical method. Results obtained for the sodium atom in the same energy region but in parallel electric and magnetic fields represent the first obtained for any non-hydrogenic atom in such combined fields above the classical ionization threshold.
