    "abstract": "We consider the process of double photoionization (DPI) in a rare gas atom as\na two-step process, namely (i) photoionization in an inner shell followed by\n(ii) the emission of an Auger electron from an outer shell. An angular\ncorrelation function for the two emitted electrons is defined by analogy with\nthe theory of angular correlation in nuclear physics. An expression is obtained\nfor this angular correlation function by a statistical method which makes use\nof the density and efficiency operators. The latter takes care of the\nattenuation of the probability of detection of an electrons due to the\ngeometrical properties of the detector. Theoretical values of the angular\ncorrelation function are obtained for DPI in xenon and these are shown to be in\ngood agreement with the experimental results given by K\\\"{a}mmerling and\nSchmidt.",
