Abstract

The KLL Auger spectrum of rubidium following the electron capture (EC) decay of 83Sr and
\n85Sr isotopes was experimentally studied in detail for the first time using one 83Sr source and
\nthree 85Sr sources in different host matrices. Energies, relative intensities, and natural widths of
\nall the nine well-resolved basic spectrum components were determined and compared with both
\npredictions and experimental data for krypton. The results of our multiconfiguration Dirac–Fock
\ncalculations demonstrated an influence of the ‘atomic structure effect’ on absolute energies of the
\nKLL transitions following the creation of initial vacancies by the EC decay. Environmental
\neffects on the KLL Auger spectrum were distinctly observed only for the absolute transition
\nenergies.
