Abstract

In the argon-helium plasmas, the emission lines of singly-ionized copper, which cannot be excited in the pure argon plasma, can be observed in the visible wavelength region. These lines are identified to the 3d94f-3d94d, 3d95d-3d95p, or 3d96s-3d94p transitions. The collisional reactions occurring and the resonance energy transfer between copper atoms and helium ions are a feasible mechanism for the observed excitations.
