چکیده انگلیسی
Ll, Lα, Lβ and Lγ1 X-ray fluorescence cross-sections for 74W have been measured at excitation energies of 12, 14, 15 and 16.5 keV using synchrotron radiations. A Peltier cooled Vortex solid state detector (SII Nano Technology, USA) with an energy resolution of 138 eV at 5.96 keV X-rays was employed for analysis. The experimental results were compared with the theoretical estimates of Krause (1979), Campbell (2003) and Puri et al. (1993) and also compared with existing experimental results (Barrea and Bonzi, 2001b) of L XRF cross sections at the excitation energy of 12 and 14 keV. Present results were found to be closer to the Puri's data in comparison to existing experimental results. For the first time, to our knowledge, L XRF cross section for 74W at energies 15 and 16.5 keV are also being reported here.
