【 摘 要 】

The radiative electron capture into highly charged lithium-like U89+ions is studied in the framework of the density matrix, based on Dirac's equation. Emphasis is placed on the population of 1s22s2p3/2J=1,2 excited states, as well as the angular distribution and polarization of subsequent characteristic photon emissions (included E1 and M2 transition).
