Title:	Evaluation of double electron capture by bare nucleus
Abstract:	We present the calculation of cross section for radiative double electron capture (RDEC) by a bare nucleus followed by emission of a single photon. The radiative double electron capture process is a time reversed process of the double electron ionization by a single photon. The calculation is performed relativistically within the framework of quantum electrodynamics (QED). In our calculations we use the Line profile approach (LPA). As the radiative double electron capture is explained by the electron correlation, corrections to the interelectron interaction were calculated with high level of accuracy. In the present calculation the interelectron interaction is taken into account partly to all orders of the perturbation theory. The calculation is performed for a wide range of nuclei.The total and differential (with respect to the direction of the emitted photon) cross sections are calculated. The results are compared with available experimental and theoretical data.
