Abstract
The Auger spectra of theM 2,M 3,M 4,M 5 subshells of krypton and the Coster-Kronig spectra of theM 1,M 2,M 3 subshells of krypton were measured with an electrostatical spectrometer. The ionization in theM shells was caused by electron impact. The use of a gaseous target made it possible to measure the Auger lines even at energies as low as 25 eV. The absolute energies and relative intensities of a great number of transitions were determined: 22 of theM 4, 5 spectrum, 14 of theM 2, 3 spectrum and 2 of theM 1 spectrum. Only in the case of theM 2, 3 spectrum a comparison between the relative intensities, determined experimentally, and those calculated byRubenstein forZ=47 was possible. The agreement is only qualitatively. Moreover, from the Auger electron energies measured, the following binding energies were calculated:E(M 1)=(292,1±1,0) eV,E(M 2)=(222,1±0,6) eV,E(M 3)=(214,6±0,6)eV,E(N 1 N 1)=(62,81±0,05) eV.
