Nickel has an absorption edge at 149 pm, between the two copper lines. Thus, using nickel as a filter for copper would result in the absorption of the slightly higher energy 139 pm x-rays, while letting the 154 pm rays through without a significant decrease in intensity. Thus, a copper X-ray source with a nickel filter can produce a nearly monochromati… falsishWebJun 13, 2016 · Hi you cant find the particle size directly.

WebChoice of X-ray Target. The wavelength, λ, of the characteristic line giving rise to a particular transition is given by Moseley's Law: 1 / λ = c (Z - σ) 2 where c and σ are constants, and Z is the atomic number of the metal used for the anode.
