X-ray studies of relativistic heavy-ion--atom collisions allow the direct observation of the radiative-electron-capture photons. The angular distribution of these photons is approximately sin/sup 2/theta/sub lab/, because of the cancellation of electron retardation effects when the cross sections are subjected to Lorentz transformation into the laboratory frame. Comparison of measured and calculated cross sections reveals the number of equilibrium projectile K vacancies present in the solid targets, which can be compared with charge-state measurements behind the target.
