Abstract :
Angular distribution and spin polarization parameters of all five Rydberg series of double-excitation resonances in the photoionization of the Be atom are calculated in the multiconfiguration relativistic random-phase approximation. Energies and widths of these resonances are compared with available data of other theories and with experiment.
