类硼离子C^(1+)的电子碰撞电离──单通道截面的共振增加

Electron Impact Ionisation of B-like Ion C^(1+)─Resonance Enhancement of Single-channel Cross Section

使用R-矩阵方法，在库仑-玻恩非交换近似下采用三态密耦图像，计算了类硼离子C1+的电子碰撞电离截面，给出了总的能量微分截面及分波能量微分截面．计算结果揭示了明显的Rydberg系列共振，并指出共振对截面的贡献大于直接电离过程对截面的贡献，这与Chidichimo的结论相一致．

Using R-matrix method the electron impact ionization cross sections of B-like ion Cl+ were calculated in the Coulomb-Born non-exchange approximation, and the single differential cross section is given. Our calculated results indicated the Rydberg series of resonance. The resonance enhancement of the single-channel cross section is significantly greater than that of the direct ionization cross section. It's in agreement with that of Chidichimo.
