Unitarization for a relativistic distorted-wave approximation has been made by using two types of scattering matrix for reactance matrix and the electron-impact excitation cross sections for Ar and Ar${}^{+}$ are calculated by the unitarized relativistic distorted-wave method. The unitarization by using the scattering matrix obtained from diagonalization of the reactance matrix significantly reduces the cross sections rather than by using the scattering matrix given from inversion of matrix related to the reactance matrix which brings out better agreement with other more sophisticated R-matrix prediction and experiments at intermediate electron energies for Ar. The cross sections for Ar${}^{+}$ by the effective unitarization are smaller than those by available other prediction using perturbative relativistic distorted-wave approach.

通过使用两种类型的散射矩阵作为电抗矩阵以及Ar和Ar的电子冲击激发截面，对相对论的失真波近似进行了单位化。${}^{+}$用统一的相对论畸变波法计算。通过使用从电抗矩阵的对角线化获得的散射矩阵进行单位化，可以显着减小横截面，而不是通过使用与电抗矩阵相关的矩阵求逆获得的散射矩阵，可以更好地与其他更复杂的R矩阵预测和在中等电子能量下进行Ar的实验。Ar的横截面${}^{+}$ 有效单位化的结果要小于使用扰动相对论失真波方法的其他可用预测结果。
