X-ray filter
An X-ray beam from a tube with molybdenum anode (?=42) at an acceleration voltage of ?=60 kV contains, besides the braking continuum, a distinct ?? peak at 0.71 Å and a smaller ?? peak at 0.63 Å. To filter out the ?? line for diffraction experiments, a zirconium filter (?=40) can be used. Justify this with the help of Mosley's law and draw the X-ray spectrum of molybdenum superimposed with the absorption effect of zirconium.
Is the main part of the braking continuum also filtered out?
