Auger electrons emitted from doubly excited states of C{sup 4+}(2{ital l}2{ital l}{prime},2{ital l}3{ital l}{prime},2{ital l}4{ital l}{prime},2{ital l}5{ital l}{prime}) formed by transfer excitation in collisions of C{sup 5+}(4--10 MeV) with H{sub 2} and He were studied using high-resolution zero-degree Auger electron spectroscopy. The {ital KLL}, {ital KLM}, {ital KLN}, and {ital KLO} resonant-transfer excitation (RTE) cross sections were measured. The impulse approximation theory with alignment and interference effects taken into consideration was found to be in reasonable agreement with the experimental data. The theory was normalized by a typical factor of 0.65 to obtain the best fits to the data. The RTEA resonance strengths were evaluated to investigate the {ital n} dependence ({ital n}=2,3,4,5) of RTEA, which is RTE followed by Auger electron emission.
