With a new method to determine the impact-parameter dependence, P (rho), of K-shell vacancy production, which ultilizes a kinematic analysis of Doppler-broadened x-ray lines, we show that the K-shell excitation probability in heavy collision systems of Coulomb barrier energies is both large and narrowly peaked at small impact parameters. In particular, for 1ssigma excitations, P (rho approx. = 0) can exceed a few percent with approximately half the total cross section contributed by collisions with rho 9 or approx. = 40 fm.
