Calculation of the correlation, relativistic and QED corrections to the total electron binding energy in atoms and their nuclear charge dependence
Abstract
We present relativistic many-body calculations of total electron binding energy of neutral atoms up to element Z=120. Binding energy for ions may be found by subtracting known ionization potentials. Accuracy of the results for 17<Z 105 significantly exceeds that in NIST tables (there are no data for Z>105 there). We fit numerical results for binding energies by analytical function of Z. We also calculate numerical values and determine dependence on Z of the correlation corrections, Dirac and Breit relativistic corrections and quantum electrodynamics (QED) corrections.
