Ab initio potential energy curves and coupling matrix elements of the molecular states involved in the collision of the N 4+ (2 s ) 2 S and B 3+ (1 s 2 ) 1 S multicharged ions on the helium atom or molecular hydrogen have been determined by means of configuration interaction methods. The total and partial electron capture cross‐sections have been evaluated in the frame of a semiclassic approach in the 1‐ to 100‐keV laboratory energy range and compared to experimental data. A comparative study of both targets is performed in the case of the B 3+ ion. © 2002 Wiley Periodicals, Inc. Int J Quantum Chem, 2002
