(2) The neutrons produced in a reactor are known as thermal neutrons, because their kinetic energies have been reduced (by collisions) until K = 3kT, where T is room temperature (293 K). (a) What is the kinetic energy of such neutrons? (b) What is their de Broglie wavelength? Because this wavelength is of the same order as the lattice spacing of the atoms of a solid, neutron diffraction (like X-ray and electron diffraction) is a useful means of studying solid lattices.
