Radioactive sources used were prepared by ion implantation of 83Sr into a high purity polycrystalline platinum foil at 30 keV and by vacuum-evaporation deposition of Rb-83 on the same type of foil. From the measured conversion electron spectra, the electron binding energies for the K, L1, L2, L3, M1, M2, and M3 shell/subshells of krypton in the platinum host were determined to be 14316.4(12), 1914.3(9), 1720.3(9), 1667.6(9), 281.5(9), 209.6(13), and 201.2(15) eV, respectively, and those for the evaporated layer were observed to be lower by 0.7(1) eV. For both host matrices, values of 2.3(2), 4.6(2), 1.7(2), 1.3(2), and 3.2(3) eV were obtained for the krypton K, L1, L2, L3, and M1 natural atomic level widths, respectively. The absolute energies of 10838.5(9) and 10839.5(10) eV were measured for the KL2L3(D-1(2)) Auger transition in krypton implanted in Pt and generated in the evaporated rubidium layer, respectively. A value of 601.0(8) eV was measured for the energy difference of the KL2L3(D-1(2)) transitions in Rb and Kr in the Pt host.
