They were used to first detect the existence of nuclei in the gold foil experiment by Ernest Rutherford.
On lunar missions, X-rays and these entities are detected by the same method: wafers of silicon. George Gamow explained their creation using quantum tunneling. These particles are used in smoke detectors, typically being produced by Americium. They were used to first detect the existence of nuclei in the gold foil experiment by Ernest Rutherford. Name these heavy decay particles that contain two protons and two neutrons.
