Charge exchange of He+, Ne+ and Ar+ in internal states of cadmium and zinc ions at low energies
We investigated experimentally the charge exchange of He+, Ne+, and Ar + in internal excited states 4rf95s2 20з/2,5/2 of Cd II and 3d94s2 2D3n of Zn II in the energy interval 2-400 eV. It is established that the interacting particle pairs are characterized, at appreciable energy defects ~ 7eV, by high energy-transfer efficiency (~ 10~16 cm2) and their charge-exchange cross sections exhibit a qualitatively different behavior at low energies. Calculation shows that the charge exchange makes a noticeable contribution to the population of the upper laser levels for λ = 4415 A He-Cd lasers and λ = 5894 A He-Zn lasers.
