The multiconfiguration relativistic random-phase-approximation theory is applied to autoionizing levels of the neutral zinc atom between 4s1/2 and 4p3/2 ionization thresholds. There are five Rydberg series of doubly excited states that manifest themselves as autoionization resonances in the 4s photoionization cross section. Theoretical predictions for the positions and profiles of the autoionization resonances are in excellent agreement with experiment.
