论文摘要
通过计算KR原子和光子能的基底态的总光电离横截面之间的相关性，在这项工作中确定了接近1.75 KeV的近乎内部轨道能量，1.75 keV，1.90 keV和14.30 keV。通过实现蒙特卡洛方法并优化光子通量建模参数，可以实现17.50 keV光子能量下的动力学模拟。结果，我们计算出的数据与实验现象更加一致。使用优化的光子通量模型理论进一步计算并研究了KR在1.75 KeV，1.90 KeV，14.30 KeV和17.50 KeV Energies的光饱和现象。我们从统计学上比较了这四个特定光子能量下的主要电离路径，并计算各种空心原子的种群变化。结果表明，在临界电离光子能量上产生的空心原子的比率很高。此外，位置的变化是平稳的，显示了低光子能量的离子的发电模式与具有高光子能的生成模式之间的显着差异，这对于研究中和高电荷状态的空心原子具有重要的参考意义。
By calculating the correlation between the total photoionization cross-section of the ground state of the Kr atom and photon energy, three particular photon energies close to the near inner orbital energy of 1.75 keV, 1.90 keV, and 14.30 keV are determined in this work. The dynamical simulation under 17.50 keV photon energy in the experimental conditions is achieved by implementing the Monte Carlo method and optimizing the photon flux modeling parameters. As a result, our calculated data are more consistent with the experimental phenomena. The light saturation phenomenon of Kr at 1.75 keV, 1.90 keV, 14.30 keV, and 17.50 keV energies is further calculated and researched using the optimized photon flux model theory. We statistically compare the main ionization paths under those four specific photon energies and calculate the population changes of various hollow atoms. The results demonstrate that the ratio of hollow atoms produced at the critical ionization photon energy is high. Furthermore, the change of position is smooth, showing the significant difference between the generation mode of ions with low photon energy and those with high photon energy, which has important reference significance for studying hollow atoms with medium and high charge states.
