Abstract

By using synchrotron radtation to excite calcium atoms in the 3p-3d resonance region, excited calcium ions are generated. In the first measurement of this kind, we have measured the polarization of the fluorescent photons which result from the decay of these ions, in coincidence with the corresponding angle-resolved photoejected electrons. By combining this with the angular distribution parameter for these same electrons, measured in a separate experiment, we are able to calculate for this specific case, within the assumption of LS coupling, the ratio of the dipole amplitudes for the outgoing waves and their phase difference.
