As part of a broader campaign to understand gamma-induced charged particle emission with multiple materials, the cross sections of the (𝛾, p), and (𝛾, 𝛼) reactions on a natural zinc target were measured using the SIDAR detectors – a subset of the ORRUBA suite of silicon detectors, and data acquisition system. These cross sections were measured experimentally using a kinematically-complete, event-by-event methodology, using monoenergetic gamma ray beams from the High Intensity Gamma Source (HI𝛾S) facility, ranging from 10 to 19 MeV, to bombard a natural metallic zinc target in vacuum. The measured cross sections are compared with theoretical predictions using the statistical model approach, which is important for the use of such models in real-world applications such as the production of the 67Cu theranostic via the 68Zn(𝛾, p) reaction.
