Chadwick experiment neutron
WebMay 8, 2024 · Chadwick’s Experiment: Neutron was discovered by Sir James Chadwick in 1932. He performed the same experiment performed by Frederic Joliot-Curie and Irene Joliot-Curie and used different bombardment targets other than paraffin. He fired alpha radiation at the beryllium sheet from a polonium source. Webevidence is in favour of the neutron, while the quantum hypothesis can only be upheld if the conservation of energy and momentum be relinquished at some point. J. Chadwick. …
