Keywords: inner shell excitaion and de-excitation, x-ray fluorescence, photon induced x-ray emission, elemental analysis of samples using xrf tecnique

Brief description of the work:
(1) Measurements of K shell fluorescence yields in the elements in the range Z = 42 to 68using two different version of a method based xrf excitation.
(2) L xray fluorescence cross-sections have been generated from the semi empirical fit to the existing experimental values to provide the values where theoretical or semi-empirical data on fundamental parameters are not available and also the experimental measurements have not been made.
(3)Alignment parameter for L3 vacancy state from the energy depenence of xrf cross-section ratios have been calculated.
(4)Elemental analysis of the rice sapling using xrf technique have been done.Also the matrix effects in the determination of elements present in rice saplings have been investigated.
