【 摘 要 】

The X-ray satellites are caused by transitions in atoms which are doubly ionized or multiply ionized. To explain the origin of X-ray satellites, the relative intensities of the various possible transitions between the doubly ionized initial and final states of an atom, have to be calculated. The intensity can be calculated from the probability of creation of the double vacancy states. These probabilities are due to Coster-Kronig and Auger transitions and can be calculated using the tables of McGuire. These tables are based on non-relativistic calculations. The latter calculations of transition probabilities are of Chen et al., who have done relativistic calculations in elements with 18 ≤ Z ≤ 96. The aim of the present work is to study the variation with atomic number (Z) of the transition probabilities for the different Coster-Kronig transitions as given in McGuire's tables and Chen et al's tables and to discuss the difference between the two calculations. The present study shows that for calculation of the intensity of a satellite, the tables of Chen et al. should be preferred over the tables of McGuire while investigating the origin of L-emission satellites.
