The relative yields per carbon atom of continuum electrons captured by 0.6--2.5-MeV/u H/sup +/ and 0.5--0.8-MeV/u He/sup 2+/ projectiles from gaseous hydrocarbon targets are observed to decrease with increasing numbers of carbon atoms and with decreasing projectile velocity. For isotachic H/sup +/ and He/sup 2+/, the relative yields are the same. Assuming i-italicn-italict-italicr-italica-italicmolecular electron-outscattering processes, additivity failure in electron capture to the continuum and its dependence of the projectile energy and molecular size can be reproduced by incorporating electron-scattering cross sections into a geometrical outscattering model.
