Description
The ratio of total double to total single ionisation cross sections, R, by high velocity projectiles containing electrons is examined in the first Born approximation. For ionisation of helium by H+, H0 and He0 impact, it is found that RH+<RH0<RHe0. Connection with Bohr's free-collision model for collisions with projectile electrons is given. (author)
