9.9
Relating to reactions in the central part of an atom caused by very strong light like gamma rays
  • adjective
  • /ˌfoʊtəˈnuːklər/
  • Specialized
: fotonuclear
  • Researchers study photonuclear processes to understand the interactions between gamma rays and atomic nuclei.

Examples

  • In some photonuclear reactions, the energy of the incident gamma can be calculated from the final nuclear state.

    Academic text (2005)
  • The target is surrounded by a detector that records particles produced in the photonuclear reactions.

Morphology

photonuclear = photon + nuclear (semi-transparent) = photon + nuclear

The meaning is compositionally related to 'photon' and 'nuclear', but it is a specialized scientific term rather than an everyday transparent compound.

Etymology

Photonuclear comes from two parts: photo- (a Greek root meaning 'light', the same 'photo' you see in photograph) and nuclear (from 'nucleus', meaning 'core' or 'center'). So a photonuclear reaction is when very strong light particles called photons hit an atom's core and cause a nuclear change.
