PHOTOIONIZATION CROSS SECTION CALCULATIONS OF Eu AND ITS IONS Eu+ AND Eu++ M.Ya.Amusia, L.V.Chernysheva and V.K.Ivanov A.F.Ioffe Physical-Technical Institute, St.Petersburg,Russia St.Petersburg State Technical University, St.Petersburg,Russia Partial and total photoionisation cross sections and photoelectron angular distributions for Eu, Eu$^+$ and Eu$^{++}$ are calculated within the Spin-Polarised Random Phase Approximation with Exchange. In the vicinity of the $4d^10$ thresholds the giant autoionizing resonance is shown to be dominated. Comparison with recent experimental data on Eu$^+$ is performed.
