Introduction .—The conception of the nuclear constitution of atoms arose initially from attempts to account for the ... intense electric or magnetic fields exist within the atom. To account for these results, it was found necessary to assume that the atom consists of a charged massive nucleus of dimensions ... ordinarily accepted magnitude of the diameter of the atom. This positively charged nucleus contains most of the mass of the atom, and is surrounded at a distance by a ... α-particle in an encounter with a single atom happens when the particle passes close to the ...
