We propose a new method for experimentally measuring the electron attenuation length in solid from Auger electron spectroscopic analysis on the aslant-smoothed surface of a metallic multilayer system. The demonstration is performed for the electrons with kinetic energies corresponding to Auger transitions using a ring pattern sputtered surface of Fe and Si0₂ multilayers. The obtained attenuation lengths are qualitatively in good agreement with the Seah-Dench formalism as well as the TPP-2 formalism for a kinetic energy region of 50 to 1600eV. The experimental values are quantitatively larger than the theoretical ones for Si₀₂, but smaller than those for Fe.
