Description

This work presents the results of Monte Carlo simulation of the
experimental setup for study the Compton scattering of annihilation
photons in GEANT4. The pair of entangled annihilation photons is born as
a result of electron-positron annihilation at rest. The experimental
setup consists of Compton polarimeters that include the plastic
scatterers and two groups of NaI(Tl) detectors of scattered gammas
azimuthally situated around the setup axis. The energy deposition
spectra in Compton scatterers and NaI(Tl) detectors are studied. The
behavior of the azimuthal correlations of the scattered photons were
obtained for a few different cases: a) a pair of photons with random
polarizations b) photons with mutually orthogonal polarizations c)
photons in a state of quantum entanglement. Clear distinctions in
azimuthal correlations for these cases are observed in simulation that
allows the comparison the experimental results with the theoretical
predictions.
