photoproductionn.

Brit.

/ˈfəʊtə(ʊ)prəˌdʌkʃn/, U.S.

/ˈfoʊdəprəˌdəkʃ(ə)n/

Origin: Formed within English, by compounding. Etymons: photo- comb. form, production n.

Etymology: < photo- comb. form + production n. Compare earlier photoproduct n.

1. Particle Physics. The production of one or more particles by the action of an incident photon.
