Abstract

For five autoionization resonances of Sr in the 4p excitation region, we have determined the ratios of five amplitudes and one phase difference for the photo-ejected electron waves which leave the Sr+ ion in the 5p 2P1/2,3/2 excited states. The technique employed is a combination of conventional angle-resolved photoelectron spectroscopy, and angular correlation measurements between photoejected electrons and polarized fluorescent photons. We discuss how the ratios of the dipole amplitudes are related to the spectroscopic descriptions of the resonances studied.
