摘要：

Coincidence measurements have been performed of double photoionization in atomic Ca in the region of the Ca 3p-3d resonance. The two electrons have been detected with equal and unequal energies and coincidences observed over a range of angles between the two electrons from approximately 90 degrees-270 degrees. Two pairs of lobes are observed in comparison with the single pair of lobes observed in the TDCS for He. Comparisons are made with the theoretical data of Ceraulo et al.
