论文摘要
研究了在恒定交叉电磁场中类似氢原子或离子的相对主义强场电离。过渡幅度在Göppert-Mayer仪表中的强场近似值内配制,其初始和最终电子状态分别由相应的Dirac-Coulomb和Dirac-Volkov波函数描述。通过将既定方法调整为当前情况,可以考虑到隧道过程中对电子运动的库仑校正。计算总和能量分化的电离速率,并将其与其他理论的预测进行比较。
Relativistic strong-field ionization of hydrogen-like atoms or ions in a constant crossed electromagnetic field is studied. The transition amplitude is formulated within the strong-field approximation in Göppert-Mayer gauge, with initial and final electron states being described by the corresponding Dirac-Coulomb and Dirac-Volkov wave functions, respectively. Coulomb corrections to the electron motion during tunneling are taken into account by adjusting an established method to the present situation. Total and energy-differential ionization rates are calculated and compared with predictions from other theories in a wide range of atomic numbers and applied field strengths.
