【Abstract】 Several fitting methods that are applied on the γ spectrum to determine the light output of low light yield scintillators were compared with Monte Carlo simulation and real data. Deviations of the light yield to fitting values from different methods are evaluated. The stability of the fitting methods in the cases of varying background and varying fitting range is also studied.更多还原
