Surrounding this tiny central core were electrons, and the distance at which they orbited determined the size of the atom. In the fall of 1901, he started studying mathematics and physics at the university in Erlangen. One scientist who was skeptical of this model of atoms was Rutherford, who won the Nobel Prize in chemistry for his 1899 discovery of a form of radioactive decay via -particles two protons and two neutrons bound together and identical to a helium-4 nucleus, even if the researchers of the time didn't know this. Moving in 1912 to the Physikalisch-Technische Reichsanstalt (German National Institute for Science and Technology) in Berlin, Geiger continued his studies of atomic structure.
