Determination of L absorption edge

  1. Dec 28, 2013 #1
    1. The problem statement, all variables and given/known data

    In uranium (Z=92) the K absorption edge is 0.107 Å and the Kα line is 0.126 Å. Determine the wavelength of the L absorption edge.

    2. Relevant equations

    K-edge: EK= (Z-1)2*13.6
    L-edge: EL= (Z-σL)2*13.6*1/4
    what is σ and how was calculated.
    Characteristic X-rays: Ex = h*ν= h*c/λ= ΔEkin = Ekin(i)-Ekin(f)
    Bremsstrahlung: Emax=Ekin(i)
    3. The attempt at a solution
    λL= 0.71 Å
