ESR Studies of Cu, Ag, and Au Atoms Isolated in Rare-Gas Matrices

Abstract

Electron spin resonance spectra were observed on Cu, Ag, and Au atoms isolated in Ne, Ar, Kr, and Xe matrices at ∼ 4°K. The hyperfine coupling constants and the g values were determined and examined for the matrix effect. With xenon matrices a superhyperfine structure with magnetic xenon nuclei was partially resolved, and by means of computer simulation, it was shown that these atoms are substitutionally incorporated within the Xe lattice. Also an evidence for atom-vacancy pairing was observed for Cu in Ne matrix.
