The continuum-distorted-wave–Born-initial-state (CDW-BIS) approximation for the description of single-electron capture from helium-like atomic systems by completely stripped projectiles is presented. The theoretical total cross-sections for charge exchange in α- and - collisions are reported in the energy range 50–2000. We also report the results obtained by means of the continuum-distorted-wave–Born-final-state (CDW-BFS) approximation. Detailed computations for differential cross-sections are performed for - collisions at 500 and 200. A comparison between the four-body one-channel distorted-wave approximation and three-body distorted-wave (CDW-3B) approximation is made for differential cross-sections at 200. The validity of our findings is critically assessed in comparison with the available experimental data.
