Abstract

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 measure the ratio of the TDCS at resonant and non-resonant photon energies of 31.41 and 43.03 eV respectively and a ratio of (3800±2100) : 1 was obtained.
