Electron capture in He{sup +} + CO collisions is considered to be one of the dominant processes causing He{sup +} ion disappearance in the astrophysical environment. The authors have investigated this process theoretically by using the diatomics-in-molecules (DIM) method for adiabatic potential surfaces and the quantum-mechanical close-coupling method for collision dynamics. Because of the strong dipole moment of CO, the adiabatic potential surfaces are strongly dependent on the molecular orientation of the CO molecule along the collision plane, and collinear formation of He{sup +}-CO is most effective for electron capture.
