The information depths of AEAPS and DAPS for the Ti and Cr L_{3}, L_{2} and L_{1} subshell excitation and of AES for the Ti L_{3}M_{2,3}M_{2,3}, L_{3}M_{2,3}M_{4,5} and Cr L_{3}M_{2,3}M_{4,5} transitions were determined. A set of Cr samples with Ti overlayers had been prepared in situ. Measurements of the LEAPS and HEAPS signal amplitudes were used to derive the AEAPS and DAPS signal intensities. The results showed that both AEAPS and DAPS had lower information depths compared with AES. They are interpreted in terms of the mean free paths of the majority of electrons contributing to the AEAPS signal.
