Accelerated electron beams are often used to study surfaces and other features of materials. Suppose one had an electron accelerator that was useful for producing electron beams used to study the features of atoms on the surfaces of solids, but wanted to alter the design to produce beams appropriate for the study of the nuclei of those atoms. What would be the appropriate alteration?
A. Increase the beam intensity B. Decrease the beam energy C. Decrease the beam intensity D. Increase the beam energy E. Increase the transverse beam size F. Decrease the transverse beam size
