Coincident energy and angular distributions in xenon 4d_5/2 inner-shell double photoionization.

We report on measurements of the triply differential cross section for the 4d(5/2) inner-shell photoionization in xenon followed by N(5)O(2,3)O(2,3) Auger decay using electron-electron coincidence spectroscopy. The experimental setup made it possible to obtain the first coincident angular distributions for the (1D2) and (3P2) final states at a photon energy of 97.45 eV. Relative amplitudes and phases describing the photoionization were estimated from these angular distributions
