6. a. X ray are produced in a tube operating at 20.0 kV strikes a target and Compton- scattered through an angle of 90.0° What is the wavelength shift, AA. b. A beam of protons with have the same energy scatters from atoms that have a spacing of 0.150 nm in the crystal. The m- 2 intensity maximum occurs when the angle is 30.0°. Calculate the kinetic energy (in eV) of each beam.
