Query: Angular correlation theory for double photoionization in a rare gas atom
  : ionization by polarized photons   This is a sequel to an earlier article on the theory of angular correlation
for double photoionization. Here we consider the two-step double
photoionization of a rare gas atom under the influence of a polarized photon
beam described by appropriate Stokes parameters. Cylindrical mirror analysers
(CMA) are used to detect the outgoing electrons. Theoretical values of the
correlation functions are obtained for linearly polarized light. Two different
situations is handled. Once, the value of the correlation function is obtained
keeping the photo-electron in a fixed direction. The other case the direction
of the Auger electron is kept fixed. Comparison with experiments on xenon shows
excellent agreement for the case of (4d_{5/2}) photoionization followed by a
subsequent (N_{5}-O_{23}O_{23} ^{1}S_{0}) Auger decay for a polarized incident
photon of energy (94.5eV) {[}J. Phys.B,
