Popis:	Photoionization parameters in neutral beryllium are calculated in the multiconfiguration relativistic random-phase approximation to resolve the interplay between relativistic and correlation effects in low-Z atoms or ions. Precise energies and widths of all five Rydberg series of low-lying doubly excited states (2pns)3,1Po1, (2pnd)3,1Po1 and (2pnd)3Do1 are given. Experimental studies on angular distribution of photoelectrons are suggested to obtain information on widths of some states, which cannot be obtained from total cross-section measurements.
