     (2) The 4d9s2 configuration in Cd+ and 3d9s2 in Zn+ are strongly excited and it means that CT collision has important contribution to the population inversion mechanism of 441.6 and 325.0 nm laser lines in Cd+ and of 747.9 and 589.4nm lines in Zn+.
     2.发现这种碰撞能强烈地激发Cd~+的4d~95s~2组态和Zn~+的3d~94s~2组态,对应的能量亏损远大于1eV。 因此,电荷转移碰撞对Cd~+的441.6和325.0nm及Zn~+的747.9和589.4nm的激光谱线有重要的贡献。

The charge-transfer collision spectroscopy of He+-Cd and He+-Zn were studied by using crossed-beam technique. The results may be divided into two parts: (1) The resonant collision cross-sections for the energy defect less than 1 eV, which are consistent with the known theory; (2) The 4d9s2 configuration in Cd+ and 3d9s2 in Zn+ are strongly excited and it means that CT collision has important contribution to the population inversion mechanism of 441.6 and 325.0 nm laser lines in Cd+ and of 747.9 and 589.4nm...

The resonant CT collision followed by cascade radiation may be responsible to this contribution.

用交叉束技术研究了He~+-Cd和He~+-Zn的电荷转移碰撞光谱。得到的结果可以分成两部分:1.证实了在能量亏损小于leV时存在着共振的碰撞截面,符合已有的理论计算;2.发现这种碰撞能强烈地激发Cd~+的4d~95s~2组态和Zn~+的3d~94s~2组态,对应的能量亏损远大于1eV。因此,电荷转移碰撞对Cd~+的441.6和325.0nm及Zn~+的747.9和589.4nm的激光谱线有重要的贡献。讨论了这种反常贡献的起因,认为共振的电荷转移碰撞和接着的级联跃迁可能是主要的激发机构。
