The photoionization cross section of Be from ${1s}^{2}{2s2p}^{1}{P}^{o}$ is studied with the saddle-point complex-rotation method for photon energies from 23 to 117 eV. A full-core plus correlation wave function is used for the initial states. In the continuum, the energy and width for the singly core-excited Be-like ${1s2s2p}^{2}{}^{1}S,{}^{1}P,$ and ${}^{1}D$ states are calculated to high precision for systems with $Z=4--10.$ The Auger decay branching ratios of these states are studied to check the spin alignment theory recently proposed by Chung. These results are compared with the available experimental data in the literature.
