R. Dorner et al., CAPTURE, IONIZATION AND LOSS IN SWIFT HE-1,HE-2-HE COLLISIONS INVESTIGATED BY COLD TARGET RECOIL ION MOMENTUM SPECTROSCOPY(), Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 99(1-4), 1995, pp. 111-113
For 0.25-2MeV He2+-He and He+-He collisions we have measured the recoi
l ion momentum distribution in three dimensions for single capture, ta
rget ionisation and projectile electron loss. From these double differ
ential cross sections we obtain state selective and scattering angle d
ependent cross sections for the single capture process and are able to
distinguish between electron-electron and nucleus-electron interactio
ns for the projectile electron loss.
