Rutherford's Nuclear Transmutation

14N + 4He → 17O + 1H

概述

In 1919, Ernest Rutherford achieved the first artificial nuclear transmutation by bombarding nitrogen-14 with alpha particles to produce oxygen-17 and a proton. This proved that elements could be transformed into other elements, realizing the ancient alchemists' dream of transmutation.
