Zero-degree {ital d}{sigma}/{ital dE} and {ital d}{sup 2}{sigma}/{ital dE} {ital d}{Omega} cusp-shape and yield variations indicate substantial electron-loss--to--continuum (ELC) contributions in the electron-capture--to--continuum (ECC) spectra obtained with bare H and He {similar to}1 MeV/nucleon projectiles on hydrocarbon molecules. An {ital intramolecular} geometrical outscattering model of secondary collisions has been developed to calculate the ELC fraction of the cusp {ital f}{sub ELC}, extract the separate ECC and ELC contributions from measured projectile velocity frame cusp contours, and predict a nominal {ital Z}{sub {ital P}}{sup 3} dependence for ELC yields in agreement with experiments in our velocity range.
