Measurements of the angular distribution of photoelectrons and the associated Auger electrons, together with their angular correlation, have allowed the relative amplitudes and phases of the s and d matrix elements for 4p3/2 photoionization of Sr to

Measurements of the triply differential cross section (TDCS) for double photoionization of Ca are presented, in a photon energy region away from any resonant structure. The data differ markedly from similar data for He. An attempt has been made to me

The triple differential cross section (TDCS) for double photoionization of calcium atoms has been studied, in the region of the Ca 3p3d giant resonance, for equal and unequal energy sharing by the two electrons. The measurements were performed at two

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 ion in the excited states. The technique employed is

The yield and angular distribution of the Auger electrons from the lowest transitions in 3p photoexcited ions are measured in the photon energy range 31-34 eV. Both are strongly influenced by the resonance structure of the excitation. An analysis of

The Stirling two-photon coincidence experiment based upon the decay radiation of metastable atomic hydrogen has been applied to the measurements of angular and polarization correlations, an experimental confirmation of the Breit-Teuer hypothesis, Ein

We demonstrate that the technique of measuring the angular correlation between the photoejected electron and polarized fluorescent photon can be used to determine all the photoionization parameters for the relativistic case. Applying this technique t

A study of the photoionization of atomic calcium in the region of the resonance at 31.41 eV is described. Measurements are made of the photoelectron angular distributions and branching ratios, corresponding to the case where the ion is left in excite
