Abstract

The He(I) photoelectron spectra of As₄ and As₂ have been recorded from heated solid arsenic and copper arsenide. The spectra were interpreted with the aid of Hartree–Fock–Slater calculations. Pyrolysis of As₂ vapour has enabled the photoelectron spectrum of atomic arsenic to be recorded. The spectra obtained demonstrate the ability of photoelectron spectroscopy to monitor the vapour-phase composition above solid arsenic or a metal arsenide as a function of temperature.
