Low-energy continuum-electron emission along the beam direction, i.e., at 0{degree}, has been investigated for 1.1--6.2 keV/u 0{sup 8+} and 2.6 keV/u o{sup q+} (q = 3, 6, and 8) colliding with He. Spectra were obtained for continuum electrons associated with bound-state capture and with no projectile charge change, respectively. As for previous measurements for 3.75 keV/u 0{sup 6+} + He, continuum electrons at 0{degree} were observed only when accompanied by bound-state capture. Cross sections for these continuum electrons are found to be increasing functions of both the projectile energy and the charge state over the ranges investigated.
