The full structure of the KLL Auger spectrum of La observed in the radioactive decay of Ce-139 in a solid matrix

Popis výsledku v původním jazyce

For the first time, the KLL Auger spectrum of La (Z = 57) following the electron capture decay of radioactive Ce-139,Ce-341 in a solid source was measured. The all nine basic spectrum components were resolved and their energies and relative intensities were determined and compared with theoretical expectations. The absolute energy of 27 383.8 +/- 2.2 eV derived for the dominant KL2L3(D-1(2)) transition was found to be higher by 7.7 +/- 2.2 eV (i.e. more than 3 sigma) than a value predicted by the widelyused relativistic semi-empirical calculations by Larkins. The possible reasons for this discrepancy are discussed. Despite of less accuracy of some measured data, the predicted strong influence of the relativistic effects on the KL1L2 (P-3(0)) transition intensity was nevertheless proved.
