posted on 2024-03-01, 18:40 authored by Rahal Saaidi, Mercedes Rodríguez-Villafuerte, Héctor Alva-Sánchez, Arnulfo Martínez-DávalosAround 80% of the events are detected through multiple Compton scattering ending in photoelectric absorption. The histograms in the bottom row show the break-down of events where at least one of the coincidence photons underwent 1, 2 or 3 Compton scatterings (CS1, CS2, CS3).
