Abstract

The ratio, R, of the double ionization cross section to that of single ionization for helium by fully stripped carbon, oxygen, silicon and sulphur ions in the energy range of 2.8 to 6.3 MeV amu-1 have been measured. The data obtained using carbon and oxygen projectiles show that in this energy range R is in better agreement with the fit given by Knudsen et al. (1984) than measurements using N7+ projectiles in the energy range 10-30 MeV amu-1 and Kr36+ projectiles with energies 0.5 and 1 GeV amu-1.
