The electron impact ionization cross section of the neutral lithium atom has been calculated in a distorted wave exchange approximation. The total cross section is in good agreement with available experimental data at incident electron energies above 10 eV. Analytic fits are provided for the 1 and subshell partial cross sections.
已在扭曲波交换近似下计算了中性锂原子的电子碰撞电离截面。在入射电子能量高于10 eV时,总截面与现有实验数据吻合良好。给出了1和子壳层部分截面的解析拟合。
