L-shell alignment observed after resonant transfer and excitation in U{sup 90+} -> C collisions.
With heavy, highly-charged ions the electron-electron correlation is probed in the relativistic domain by Resonant Transfer and Excitation, RTE. For the studied case of initially He-like U{sup 90+} ions the KLL-RTE splits into three resonance groups according to the j values of the electrons involved in the doubly-excited intermediate states. For a K to L excitation into a j {prime}= 1/2 state with a simultaneous capture also to a j{prime} = 1/2 state, relativistic effects yield a strong cross section enhancement. The doubly excited states with jj{prime} = 1/2-3/2 show a strong anisotropy for the radiative ground state transition of the j{prime} = 3/2 electron manifesting a pronounced non-isotropic population of the magnetic substates.
