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 2S1/2, 5p 2P1/2 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 2P3/2 level is evaluated using the present measurement of beta and the previous fluorescence measurement of the alignment tensor A20 for Sr+ 5p 2P3/2.
