摘要：

Single electron capture cross sections have been measured for collisions between O7+ and He at energies from 1 eV/q to 1keV/q. Experimental cross sections are compared with those for H-like ions of C5+ and N6+ impacts. Cross sections for C5+ and O7+ are found to depend only weakly on the collision energy, while those for N6+ vary rather strongly. By using a velocity-dependent classical over barrier model, the energy dependency is accounted for qualitatively.
