The first section (6.2.1) considers scattering experiments as a source of evidence about the structure of atoms and nucleons. Ideas from earlier in the module are used to consider particle paths in magnetic and electric fields in the context of particle accelerators. Evidence for discrete energy levels leads on to a crude model of the atom as a particle in a box. This section gives more opportunities to discuss the development of models in physics and the international cooperation needed to fund large experiments (HSW11).
