The second-order Oppenheimer-Brinkman-Kramers approximation for relativistic electron capture is formulated, and rigorously calculated {ital K}-{ital K} cross sections are presented for the first time. Theoretical cross sections for electron capture in collisions of C{sup 6+}-Au at 400 MeV/u and Ar{sup 18+}-Ag at 400 and 1050 MeV/u projectile energy are compared with the experimental data and other approximate second Born results. It is shown that exact second Born cross sections grossly overestimate the experimental data.
