Experimental and calculated Auger electron kinetic energies (in eV) following the 3d ionization of atomic gallium

Table 2. Experimental and calculated Auger electron kinetic energies (in eV) following the 3d ionization of atomic gallium. The mean kinetic energy error was estimated to be ±10 meV. The present assignment and leading mixing coefficients for the 3d ionized states in LSJ coupling are present in the last column.

Abstract

We present an experimental and theoretical study of 3d photoionization and subsequent Auger decay of atomic gallium. The synchrotron radiation-induced electron spectra have been compared and analysed using multiconfiguration Dirac–Fock calculations. It has been shown that the theoretically predicted photoelectron spectrum is in rather good agreement with the experiment allowing us to identify the main spectral features. However, prediction of the Auger decay intensities fails due to calculational difficulties for the continuum wavefunctions of very low kinetic energy Auger electrons.
