Energy, Charge and Z Dependence of Carbon (I.E.C+Q Where Q=1,2,3)PrdjectiIe Induced L Sub Shell X-Ray Intensity Ratios in Au, Tl, Bi, Th and U Elements

摘要

Energy, charge and Z dependence of L shell X-ray intensity ratios in,the,energy range 0.9 MeV to 15 MeV has been investigated in Au, Tl, Bi,Th and U for incident carbon (i.e. C~(+q) where q=l,2,3 )projectile. The intensity ratios Iι/Iγ, αI/γI and Iβ/Iγ first decreases with increase in energy, attain minimum value and then start increasing. The minimum value of Iι/Iγ and Iβ/Iγ falls in the energy range (0.9MeV to 3MeV) and of Iβ/Iγ the energy range 6MeV to 15MeV for all elements. It has also been investigated that for a particular energy and Z, values of Iι/Iγ,Iα/Iγ and Iβ/Iγ increases witbnlecrease in value of charge (q). Similarly for particular energy and charge, values of Iι/Iγ,Iα/Iγ and Iβ/Iγ increases with increase in Z value. Also a comparison has been made among the intensity ratios evaluated using two different sets of parameters i.e. (fluorescence yield ω1 where i=1,2,3 for L1, L2 and L3 sub shells and Coster Kronig transitions fij where i,j=l,2,3 for L1, L2 and L3 sub shells) given by Krause et al and Campbell.
