The first experimental investigation of the KLL Auger spectrum of Ni generated in the electron capture decay of radioactive Cu-64 in a solid state matrix
Result description
The KLL Auger spectrum of Ni generated in the electron capture decay of radioactive Cu-64 in a solid state matrix was measured for the first time using a combined electrostatic electron spectrometer adjusted to a 7 eV instrumental resolution. Energies and relative intensities of the all nine basic spectrum components were determined and compared with data obtained from X-ray induced spectra of metallic Ni and with theoretical results as well. Absolute energy of 6562.5 +/- 1.3 eV (related to the Fermi level) measured for the dominant KL2L3(D-1(2)) spectrum line was found to be higher by 3.5 eV (2.5 sigma) than a value obtained from the X-ray induced spectra which is probably caused by the effects of chemical bonding and physico-chemical environment. Moreover, it is higher by 20.4 eV (16 sigma) than a prediction of the semi-empirical calculations by Larkins which indicates an influence of the "atomic structure effect" on absolute energies of the Auger transitions following the electron c
