TRANSITION SELECTIVE INVESTIGATION OF THE RESONANT TRANSFER AND EXCITATION IN U90-]C COLLISIONS()

Resonant transfer and excitation in highly charged uranium ions has be en investigated by applying the X-ray/particle coincidence technique. This complete detection method for the RTE process in combination with the large L-shell fine structure splitting in uranium allows, for the first time, an L-subshell differential as well as angular differentia l study of the excitation and radiative stabilization of different int ermediate electronic states. Measured L-subshell differential cross se ctions for the KLL-RTE in U90+-->C collisions compare well with full r elativistic calculations. For the radiative stabilization of the KL(1/ 2)L(3/2) intermediate states a significant anisotropy was found.
