使用最近提出的经验公式，给出了自由原子和从氢到钙（Z=20）的所有电离阶段的基态单次电离的电子碰撞电离截面。假定撞击电子呈麦克斯韦分布，给出了这些物质的电离率系数。不考虑多重电离、电离势降低或碰撞极限。
Using the empirical formula recently proposed, electron-impact ionization cross-sections for single ionization from the ground state are given for free atoms and for all ionization stages from hydrogen to calcium (Z=20). Ionization rate coefficients are given for these species on the assumption of a Maxwellian distribution of the impacting electrons. Multiple ionization, lowering of ionization potential, or collision limit are not taken into account.
