Monte Carlo calculations of the total-to-peak ratio in gamma-ray spectrometry

Monte Carlo calculations of the total-to-peak ratio for a coaxial closed end n-type gamma-ray detector were performed and the results compared to the measured values. Whereas reasonable agreement between the calculated and measured spatial dependencies was achieved, the calculation overestimates the absolute experimental values by about 10%. The spatial dependence of the total-to-peak ratio is discussed in terms of detector geometry.
