Evaluating coincidence summing factor using Marinelli beaker on coaxial HPGe detector by Monte Carlo simulation and calculating

This investigation aims to compare the full energy peak efficiencies in the energy range of 46-1836 keV on a type-p coaxial HPGe and estimate the coincidence summing factor for the case of Marinelli Beaker samples used by two general Monte-Carlo simulation software MCNP and PENELOPE.
