Total cross sections sigma 2+ for He 2+ formation from the combined processes of charge transfer ( sigma c ) and ionisation ( sigma i ) in He + -He + collisions have been measured using an intersecting beam techniques for CM energies in the range 11-113 keV. Cross sections for ionisation sigma i = sigma 2+ - sigma c are derived by subtracting the authors' recently measured sigma c values from the sigma 2+ data. The results are compared with data extracted from previous experimental measurements of Peart et al (1983) in the range 14-58 keV and with theoretical predictions.
