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. From this equation it can seen that as the atomic number of the target increases, then the wavelength of the … WebIncreased superficial hardness provides excellent machineability Temperature: -40°C up to +105°C.
