摘要:

The spatial distribution of Cr deposited on metallic surfaces at concentrations of about 1016at/cm2was examined by detecting the radiation components emitted in the51Cr decay. The autoradiography revealed a non-homogeneous Cr covering. Combined Auger electron and X-ray spectroscopies yielded information on the Cr concentration, especially in the 2 nm thick surface layer. This concentration was found to depend strongly on the chromatation procedure applied. The influence of multiple vacancies on the LMM Auger spectrum of vanadium was investigated theoretically.
