TY - JOUR A1 - Rumrich, Klaus A1 - Soff, Gerhard A1 - Greiner, Walter T1 - Ionization and pair creation in relativistic heavy-ion collisions T2 - Physical review. A N2 - Ionization, pair creation, and electron excitations in relativistic heavy-ion collisions are investigated in the framework of the coupled-channel formalism. Collisions between heavy projectiles and Pb82+ are considered for various bombarding energies in the region E=500 up to 2000 MeV/u. Useful symmetry relations for the matrix elements are derived and the influence of gauge transformations onto the coupled-channel equations is explored.
