Abstract

Cross sections for production of excited states of Cd II resulting from He⁺‐Cd and He⁺₂‐Cd collisions are reported. These data suggest that high‐pressure (∼ atmospheres) operation of a He‐Cd laser in which pumping is achieved by charge‐transfer excitation with reactant He⁺₂ might be possible. Selective population of the (4d)⁹(5s)² ²D_3/2 level in He⁺₂‐Cd collisions produces enhancement of the 325.0‐nm line relative to the 441.6 nm.
