Matrix-Isolation Spectra of Discharge “Sputtered” Metals

Abstract
Atomic Cu, Ag, Cd, and Fe are produced by bombarding the appropriate metal with positive ions from a microwave discharge. The process is similar to sputtering. The metal atoms are trapped in an inert‐gas matrix on a cold window and their uv spectra observed. This is a new method for isolating high‐melting materials in a matrix for spectroscopic study.
