磁场中氢原子正能谱的绝热基展开方法

Positive-energy spectra of atomic hydrogen in a magnetic field with an adiabatic-basis-expansion method

L. B. Zhao, K. D. Wang, K. Bartschat

摘要:

本文重新讨论了氢原子在白矮星强度磁场中的光电离问题,以了解文献中报道的各种理论方法所获得的正能谱中存在的差异。光电离的振子强度用Mota-Furtado和O 'Mahony开发的绝热基展开方法计算[Phys.Rev.A { \bf 76},053405(2007)]。在绝热基展开方法和我们先前开发的耦合通道理论[Phys. Rev. A { \bf 94},033422(2016)]之间进行比较研究。正能谱的详细分析表明,绝热基展开方法可以产生更准确的正能谱比其他报道的方法低场强。

英文摘要:

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.
