ALPHA DECAY

Specialty Definition: ALPHA DECAY

DomainDefinition

Aerospace

The radioactive transformation of a nuclide by alpha-particle emission. Also called alpha disintegration.The decay product is the nuclide having a mass number four units smaller and an atomic number two units smaller than the original nuclide. (references)

Physics

The emission of a nucleus of a helium atom from the nucleus of an element, generally of a heavy element, in the process of its radioactive decay. Source: European Union. (references)

    • The P-process

In alpha decay an atomic nucleus ejects an alpha particle and transforms into a nucleus with mass number 4 less and atomic number 2 less. For example

23892U → 23490Th + 42He

More usually written as

238U → 234Th + α

Note that an alpha particle is a helium nucleus, and that both mass number and atomic number are conserved. Essentially alpha decay can be thought of as nuclear fission where the parent nucleus splits into two daughter nuclei.
