Atomic and Plasma-Material Interaction Data for Fusion, 13 (2007), 8 - 20.

We review the status of charge exchange data for collisions between slow (impact energy below 1 a.u. = 25 keV/amu) alpha particles and some selected atoms and molecules. Because at low energies charge transfer between alpha particles and atomic hydrogen turns out to have a negligibly small cross section, low-abundant neutral atomic and molecular species with large cross section can be of great relevance for the charge state distribution of helium ions in colder plasma regions. In particular at the lower energies (E c 1 keV/amu) gaps or inconsistencies in the data are found.
