Description: The polarization correlation of coincident
gamma rays, the property of entanglement (orthogonal
polarization) of annihilation photons (511 keV), has immense
potential in positron emission tomography (PET). It can help
classify the true coincidence events amongst the scattered,
random, and multiple events. This project requires simulation
work and computer programming. The available codes (GATE,
GEANT4) can be utilized wherever possible.

EP02
Description: For the spectroscopic investigation of
nuclei, the accurate spin-parity assignment to nuclear states is
utmost crucial. Most studies in literature have focused on
finding the directional-correlation ratios (DCO) for the spin
assignment, without the simultaneous use of
polarization-directional correlation (PDCO) to ascertain the
spin-parity and mixing ratio. The project requires understanding
the available code for the theoretical PDCO analysis. The
theoretical results will be compared with the experiment to find
the spin-parity of the states.
