Measurement of total, radiative and radiationless (Auger) vacancy transfer probabilities from K to Li sub-shells of Cs, Ba and La

Abstract

The vacancy transfer probabilities of K to L1, L2 and L3 shells were measured with a new approach. The measured L X-ray yields from targets excited by 59.5 keV incident photons, i.e., above the K edge of elements, were detected with a high-resolution Si(Li) detector. For comparison with experimental results, theoretical calculations were made using radiative and radiationless transitions. The radiative transitions of these elements were taken from the relativistic Hartree–Slater model. The radiationless transitions were taken from the Dirac–Hartree–Slater model. The measured results were found to be in good agreement with theoretical values.
