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

Abstract

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=1,2,3 ) projectile. The intensity ratios I_l/I_γ, I_α/I_γ and I_β/I_γ first decreases with increase in energy, attain minimum value and then start increasing. The minimum value of I_l/I_γ and I_α/I_γ falls in the energy range (0.9MeV to 3MeV) and of I_β/I_γ in the energy range 6MeV to 15MeV for all elements. It has also been investigated that for a particular energy and Z, values of I_l/I_γ, I_α/I_γ and I_β/I_γ increases with decrease in value of charge (q). Similarly for particular energy and charge, values of I_l/I_γ, I_α/I_γ and I_β/I_γ 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 ω_i where i=1,2,3 for L₁, L₂ and L₃ sub shells and Coster Kronig transitions f_ij where i,j=1,2,3 for L₁, L₂ and L₃ sub shells ) given by Krause et al and Campbell.
