Determination of K–L total vacancy transfer probabilities using a weak gamma source in 2π geometrical configuration

The K shell intensity ratios Kβ/Kα for 9 elements in the atomic range 40≤Z≤50 have been determined using a weak 133Ba gamma source at excitation energy of 80.997 keV. The K–L total vacancy transfer probabilities (ηKL) for these elements have been determined. K x-rays emitted by samples were detected using a CdTe semiconductor detector (resolution <1.2 keV for the 57Co gamma ray at 122 keV) with a 2π solid angle. The measured values were compared with the theoretical values calculated using Scofield′s tables based on the Hartree–Slater and Hartree–Fock theories and available experimental values. - Highlights: ► In recent years, analysis of vacancy transfer probability has been increased. ► CdTe detectors have good detection efficiency and high energy resolution. ► We used a 2π solid angle and CdTe semiconductor detector to determine K x-ray fluorescence parameters. ► Our experimental values closely agree with theoretical values and other experimental values.
