Abstract

The KLL Auger spectrum of rubidium following the electron capture (EC) decay of ⁸³Sr and ⁸⁵Sr isotopes was experimentally studied in detail for the first time using one ⁸³Sr source and three ⁸⁵Sr sources in different host matrices. Energies, relative intensities, and natural widths of all the nine well-resolved basic spectrum components were determined and compared with both predictions and experimental data for krypton. The results of our multiconfiguration Dirac-Fock calculations demonstrated an influence of the 'atomic structure effect' on absolute energies of the KLL transitions following the creation of initial vacancies by the EC decay. Environmental effects on the KLL Auger spectrum were distinctly observed only for the absolute transition energies.
