## Homework Statement

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.

## Homework Equations

K-edge: E

_{K}= (Z-1)

^{2}*13.6

L-edge: E

_{L}= (Z-σL)

^{2}*13.6*1/4

what is σ and how was calculated.

Characteristic X-rays: E

_{x}= h*ν= h*c/λ= ΔE

^{kin}= E

_{kin(i)}-E

_{kin(f)}

Bremsstrahlung: E

_{max}=E

_{kin(i)}

## The Attempt at a Solution

λ

_{L}= 0.71 Å
