Germanium Rotational Measurements for Angular Correlations (GeRMAC) Coincidence System*

Gamma-rays emit isotropically from unstable isotopes, unless they are emitted successively. Successive emission of gamma-rays contain angular correlations between the direction of emission of the first and second gamma-ray. These angular correlations serve two primary applications of interest: to experimentally verify nuclear data, and correct for true coincidence summing. In our work, we aim to perform coincidence measurements between gamma-rays to experimentally calculate the angular correlations between gamma rays for various isotopes. In this talk, I will share the theoretical calculations used to predict the probability distribution of gamma-ray emissions, and early developments of our gamma-ray coincidence measurement system.
