Process in which an atomic nucleus acquires an additional particle.
Notes: - The captured particle may be an elementary particle and may be charged or neutral.
- In general, a specification is added of the type of the captured particle or its energy.
Example:
Gold-197 captures a neutron and emits a gamma ray: \(\ce{^{197}Au + n -> ^{198}Au + \gamma}\), or in short form \(\ce{^{197}Au}(\rm{n},\gamma)\ce{^{198}Au}\).
