Photoionization cross sections of the Be atom are calculated using the hyperspherical close-coupling method where a model potential is employed to approximate the screening of the 1[ital s][sup 2] closed-shell core electrons. The cross sections obtained below the Be[sup +](2[ital p]) threshold agree well with the results of other calculations and with experiment. Total and partial photoionization cross sections for photon energies between the Be[sup +](2[ital p]) and Be[sup +](3[ital s]) thresholds are also calculated.
