Question

Property of $Cu$ so that it is used as target in in X-ray diffraction (XRD)?

Answer 1

X-ray crystallography is a technique used for determining the atomic and molecular structure of acrystal, in which the crystalline structure cause a beam of incidentX-rays to diffract into many specific directions.

Actually X-ray tubes are produced with different anode materials. The nature of the material determines the wavelength produced. For copper it is reasonably long 1.54056 Å, which gives good resolution in registration of the pattern. Another standard that has been used historically for powder diffraction is cobalt with the wavelength of 1.789 Å which is even better for resolution of the reflections. The groups running both powder and single crystal diffraction studies with a single X-ray source use usually Mo Kalpha with the wavelength of 0.71073 Å.
