WebErnest Rutherford & Thomas Royds, Philosophical Magazine 17, 281-286 (1909) The experimental evidence collected during the last few years has strongly supported the view that the α particle [4] is a charged helium atom, but it has been found exceedingly difficult to give a decisive proof of the relation. WebBy Don Lincoln, Ph.D., University of Notre DameSince the atom was discovered, many theories tried to depict what an atom is like. They have likened it to a plum pudding, a small ball, and even a tiny solar system. Perhaps, it is also imagined as a core with a cloud of small and light particles surro...
