摘要：

The ratio R of helium double-to-single ionization cross sections was measured for Ne10+ and Ni28+ projectiles at velocities of 0.39 less-than-or-equal-to v(P)/c less-than-or-equal-to 0.93 intending to explore the high-velocity limit of R for highly charged ion impact. For Ne10+ projectiles R was observed to become independent of v(P) for v(P)/c greater than or similar to 0.73 and an asymptotic experimental value R = (2.57 +/- 0.10) x 10(-3) has been established. This is in good agreement with experimental results for proton, antiproton, electron, and positron impact and in excellent accordance with the theoretical prediction of (2.59 +/- 0.03) x 10(-3).
