用超弹性散射法测量了入射电子能量相当于∼10 eV和∼12 eV的电子碰撞激发钙原子的碰撞参数。导出了4 1P1态的参数Plin、L⊥和γ，并确定了相关的斯托克斯参数。计算结果与以前发表的四种不同理论的计算结果进行了比较：相对论扭曲波计算、R-矩阵计算、B-样条R-矩阵理论和收敛紧耦合理论。
Atomic collision parameters have been measured for electron impact excitation of calcium using the superelastic scattering method, at incident electron energies equivalent to∼ 10 eV and∼ 12 eV. The parameters P lin, L⊥ and γ were derived for the 4 1 P 1 state, and the related Stokes parameters determined. The results are compared to previously published calculations from four different theories: a relativistic distorted wave calculation, an R-matrix calculation, an R-matrix theory using B-splines and a convergent close coupling theory.
