Description
Summary:Pronounced surface reduction of some 3d transition metal compounds has been observed during measurements with an AEI ES200 X-ray photoelectron spectrometer. Systematic data indicate that the degree of reduction in a given compound does not depend on temperature, vacuum pressure or X-ray flux, but is a function only of the integrated X-ray dose. Particularly strong effects were found in cupric fluoride and potassium ferricyanide.
