Measurement of atomic L shell Coster-Kronig yields (f12, f23 and f13) for some elements in the atomic number range 59 ? Z ? 90

Abstract

Non-radiative transitions cause changes in the generation of the intensity of the L lines. In order to investigate the physical quantities relevant to the L lines affected by the non-radiative transitions, experimental measurements were carded out using a Si(Li) x-ray spectrometer. Atomic L shell Coster-Kronig yields (f12, f13 and f23) for some elements in the atomic number range 59 ? Z ? 90 were determined. These selected measured semi-empirical values were also fitted by least squares to polynomials in Z of the form ?n an Zn (except for f13) and compared with theoretical and with earlier fitted values.
