Abstract

Angle-resolved photoelectron spectroscopy using monochromatized synchrotron radiation has been applied to measure relative partial photoionization cross sections sigma and photoelectron asymmetry parameters beta for Sr⁺ 5s ²S_1/2, 5p ²P_1/2 and 5p ²P₃2/in the Sr 4p-4d giant resonance region. At the Sr 4p^-1 5s²4d ¹P₁ resonance photoionization, the phase difference between the s and d outgoing waves which leave Sr⁺ in the 5p ²P_3/2 level is evaluated using the present measurement of beta and the previous fluorescence measurement of the alignment tensor A₂₀ for Sr⁺ 5p ²P_3/2.
