The unknown “radiation” did not carry a charge and was not deflected by magnetic fields 2. It could not be gamma rays because the particle contained enough mass to dislodge a proton. 3. New particle –Neutron –no charge; mass ~ the same as a Proton. No new model: Quantum Mechanical Model WebHe found a green glow on the wall of his glass tube and attributed it to rays emanating from the cathode. In 1869, with better vacuums, Plücker’s pupil Johann W. Hittorf saw a shadow cast by an object placed in front of the cathode. The shadow proved that the cathode rays originated from the cathode. chinook crash 1994
