Abstract
Visible emission is observed when metastable oxygen O₂ ([MATH]) produced in a microwave discharge interacts with various heated high purity metal wires containing few ppm of copper. Spectra in the visible and the near infrared are presented. The visible spectra are identical with those obtained in subsequent copper wire experiments. These results tend to prove that CuCl₂ is not the visible emitter.
