ABSTRACT
This chapter discusses the α and • particles which suffers deflexions from their rectilinear paths by encounters with atoms of matter. The atom is supposed to consist of a number N of negatively charged corpuscles, accompanied by an equal quantity of positive electricity uniformly distributed throughout a sphere. The chapter presents the deviation of a particle throughout a considerable angle from an encounter with a single atom as 'single' scattering. The angular distribution of the α particles scattered from a thin metal sheet affords one of the simplest methods of testing the general correctness of this theory of single scattering. The chapter discusses when the theory is compared with the experimental results, it has been supposed that the atom consists of a central charge supposed concentrated at a point, and that the large single deflexions of the α and β particles are mainly due to their passage through the strong central field.
