چکیده انگلیسی
The radiative electron capture into medium- and high-Z, lithium-like ions is studied in the framework of the density matrix theory. For these few-electron ions, detailed computations have been carried out for the angular distribution of the emitted X-rays following the capture into the low-lying 1s22s2ljLJ1,3 beryllium-like levels, including the 1s22s2S01 ground state. In these computations, emphasis is placed on the many-electron effects which arise especially at low collision energies. For slow projectiles of a few MeV/u, the interelectronic effects may reduce the angle-differential cross-sections by about 5% when compared with effective one-electron calculations.
