✦ Synopsis

Recciwd 4 August 197.5 Revised manuscript rcccivcd 29 Scptcmbcr 1975

The XPS spectrum of the 4fIzvels of W in N+\VOJ bronzes is explained by sssurning the prescnca of three oxidation states (WG+, Wsc nnd \V4'). Tetravslcnt tungsten is formed by dismutation of W 5+. The partial reduction of W6+ nnd W5' during the recording of XPS spectra is briefly considered.
