L X-RAY FLUORESCENCE CROSS-SECTIONS MEASUREMENTS FOR ELEMENTS 56≤Z≤66 IN THE ENERGY RANGE 11-41 keV

The L X-ray fluorescence cross-sections (σLα;, σLβ and σLγ) have been measured for ten elements (65≤Z≤66) at various photon energies in the range of 11-41 keV. A good agreement is found between the measured results and the theoretically calculated values of L XRF cross-sections using various physical parameters based on relativisitc theory

X-RAY AND GAMMA-RAY INTENSITY MEASUREMENTS IN 177Lu AND 2l0Pb DECAYS

Relative intensities of X- and gamma-rays emitted in the radioactive decays of 177Lu and 210Pb were precisely measured using a 28.27 mm2 x 5.5 mm vertical Si(Li) detector, a 28.27 mm2 x 5.0 mm vertical planar HPGe detector and a 96.0 cm3 coaxial HPGe detector. The measured intensities of X-rays have been compared with the values deduced by using physical parameters from internal conversion and sequential atomic processes
