Episode 537: Preparation for the deep scattering and quarks topics
- know that Rutherford’s experiment, using alpha particles, cannot probe the nucleus because the alpha particles will interact with the nucleus by the strong nuclear force
- know that electrons, being leptons, do not ‘feel’ the strong nuclear force, and so can probe the nucleus
- use electron wavelength and scattering data to calculate the size of the nucleus
- understand that the complex scattering from a nucleus reveals that nucleons are not simple points, but are themselves composed of smaller particles
- describe how hadrons are made from two or three quarks
- deduce the properties of a hadron from the properties of its constituent quarks
- draw Feynman diagrams involving quarks and gluons
Rutherford’s experiment, diffraction, and the quantum nature of electrons (‘wave-particle duality’).
If you have not covered diffraction already, you will have to modify the suggested approach to take account of this.
