用二维半经典近似研究了强磁场中类氢原子的σ偏振谱。发现零场电离极限以上的共振，并计算它们的能量分离的区域从电离极限到40 h（交叉）以上的ω c，其中ω c是回旋频率，磁场为10，17，25，32，40和47千克。在电离极限下，发现共振之间的间隔为1.500 h（交叉）Ω c，与磁场强度无关，这与加顿和汤姆金斯（1969）在24 kG磁场中钡的σ极化谱中实验观察到的1.5 h（交叉）Ω c的间隔一致。的能量分离被发现减少以上的电离极限的值h（交叉）ω c，这是一个自由电子在均匀磁场中的水平的特征。
A two dimensional semiclassical approximation is used to examine the sigma polarization spectrum of a hydrogen like atom in a strong magnetic field. Resonances above the zero field ionization limit are found and their energy separations are computed over the region from the ionization limit to 40 h(cross) omega c above, where omega c is the cyclotron frequency, for magnetic fields of 10, 17, 25, 32, 40 and 47 kG. At the ionization limit the separation between resonances is found to be 1.500 h(cross) omega c, independent of magnetic field strength, which is in agreement with a separation of 1.5 h(cross) omega c observed experimentally by Garton and Tomkins (1969) in the sigma polarization spectrum of barium in a magnetic field of 24 kG. The energy separations are found to decrease above the ionization limit toward the value h(cross) omega c, which is characteristic of the levels of a free electron in a homogeneous magnetic field.
