dc.description.abstractThe knowledge of the angular dependence of M shell production differential cross-sections is important because of their extensive use in basic studies of photoelectric effect, characteristic X-ray production, internal conversion of γ-rays, radiative and non-radiative transition probabilities and development of more reliable angular dependence theoretical models describing fundamental inner-shell ionization processes. The angular dependence of M X-ray production differential cross-sections for selected heavy elements between Lu and Pt have been measured at 5.59 keV incident photon energy, at seven emission angles in the range 120° - 150° at intervals of 5°. The emission angle was set to 0°. The target M X-ray spectra were recorded by the collimated Si(Li) detector, which has an active area of 12.5 mm2, a sensitive crystal depth of 3 mm and a Be window of 0.025 mm thickness. The measured energy resolution of the detector system was 188 eV for an amplifier shaping time constant of 6 ps at the 5.9 keV peak of 55Fe. Angular dependence M X-ray production differential cross-sections have been derived, using the M-shell fluorescence yields, experimental total M X-ray production cross-sections and theoretical M-shell photoionization cross-sections. M X-ray production differential cross-sections are found to decrease with increase in the emission angle, showing an anisotropic spatial distribution of M X-rays. To the best of our knowledge, no other experimental results are available for worked elements in the angular range 120°-150° for comparison with present results. Extracted results have been compared with the theoretical predictions and semi empirical fits. The present experimental results are in good agreement with the theoretical values.tr_TR
