论文摘要
重新审视了白色紫外线强度磁场中原子氢的光离子化问题，以了解文献中报道的多种理论方法获得的正能光谱中的现有差异。通过Mota-Furtado和O'Mahony [Phys。修订版A {\ bf 76}，053405（2007）]。在绝热基础膨胀法与我们先前开发的耦合通道理论之间进行了比较研究[Phys。修订版A {\ bf 94}，033422（2016）]。对此处获得的阳性能量光谱以及其他理论方法的详细分析表明，与其他报道的低田间强度相比，绝热基础膨胀方法可以产生更准确的阳性能源光谱。
The problem of photoionization of atomic hydrogen in a white-dwarf-strength magnetic field is revisited to understand the existing discrepancies in the positive-energy spectra obtained by a variety of theoretical approaches reported in the literature. Oscillator strengths for photoionization are calculated with the adiabatic-basis-expansion method developed by Mota-Furtado and O'Mahony [Phys. Rev. A {\bf 76}, 053405 (2007)]. A comparative study is performed between the adiabatic-basis-expansion method and our previously developed coupled-channel theory [Phys. Rev. A {\bf 94}, 033422 (2016)]. A detailed analysis of the positive-energy spectra obtained here and those from other theoretical approaches shows that the adiabatic-basis-expansion method can produce more accurate positive-energy spectra than other reported approaches for low field strengths.
