Cross Sections for Electron Capture in Relativistic Atomic Collisions

Abstract

Cross sections for the capture of electrons from single-electron targets into bare projectiles moving at relativistic velocities are calculated using the relativistic eikonal approximation. The calculations are performed for projectile energies between 0.2 and l04 GeV/u and for projectile-target combinations that presumably are of interest for future experiments, namely Au and U colliding with C, Al, Cu, Ag, Au, and U and vice versa. State-to-state cross sections are given for initial and final 1s1/2, 2s1/2, 2p1/2 and 2p3/2 states.
