一个合理的完整的一套唯象离散和电离截面氩给出使用的数据和理论上有意义的外推的广义振子强度的组合。在包括内壳层截面的估计之后，考虑了Ar中电子的降解。每个激发态的最终种群的计算给出作为入射能量的函数，当施加到电离，结果在电子伏特每离子对值接近29 eV。在我们的工作中，内壳层似乎对能量超过1千伏时的损失函数贡献了5%。
A reasonably complete set of phenomenological discrete and ionization cross sections for argon is given using combinations of data and theoretically meaningful extrapolations of the generalized oscillator strengths. After including estimates of inner‐shell cross sections, the degradation of electrons in Ar is considered. Calculations of the final populations for each excited state are given as a function of incident energy and when applied to ionization, results in electron volts per ion pair values near 29 eV. Inner shells in our work appear to contribute by adding on the order of 5% to the loss function at energies above a kilovolt.
