The photoionization cross sections of the 3d, 3p, and 3s subshells of Zn i are calculated from threshold to 1000 eV. Electron-correlation effects are included using a low-order perturbation expansion obtained from many-body perturbation theory. The 3dkf cross section is also calculated in the exact single-channel random-phase approximation with exchange. Autoionizing resonances due to the 3p5ns and 3p5nd configurations are included in the 3dkf cross section, and the effect of core relaxation is considered. The effect of single-channel and multichannel correlations is included in all subshell cross sections.
