Episode 531: Neutron Diffraction

Through discussion and a worked example, these activities from the Institute of Physics, help students to look at neutron diffraction. Students calculate the de Broglie wavelength of a neutron and see the sources and uses of neutrons.

In a worked example, using the de Broglie equation, students consider the momentum and kinetic energy of a neutron to see why they are able to penetrate lead.

Students also look at neutrons in a nuclear reactor and how they are moderated.
