We have renormalized our previously reported 0{degree} cross sections for zero resonant transfer and excitation calculation using high-resolution Auger spectroscopy (RTEA), {ital d}{sigma}{sub RTEA}(0{degree})/{ital d}{Omega}, obtained in 0.25--2-MeV/u collisions of F{sup 6+} and O{sup 5+} ions with H{sub 2} by normalizing to calculated binary-encounter electron yields rather than the usual Ne {ital K} Auger yields. The renormalized data are found to be in good agreement with recent angular-dependent impulse-approximation calculations of RTE, showing the importance of alignment and the small influence of interference between RTEA and elastic electron scattering for a 0{degree} observation.
