WebIt wasn't until 1932 that the English physicist, James Chadwick, was able to prove its existence. Chadwick used a version of Rutherford's experiment, using a sheet of beryllium and a paraffin... WebDiscovery of the Neutron. It is remarkable that the neutron was not discovered until 1932 when James Chadwick used scattering data to calculate the mass of this neutral particle. Since the time of Rutherford it had been known that the atomic mass number A of nuclei is a bit more than twice the atomic number Z for most atoms and that essentially all the …
