Data of the gamma-ray spectral energy resolution calibration method

This dataset shows the plot data in our proposed gamma-ray spectral energy resolution calibration method. Energy resolution calibration is crucial for gamma-ray spectral analysis, as measured using a scintillation detector. A locally constrained regularization method was proposed to determine the resolution calibration parameters. First, a Monte Carlo simulation model consistent with an actual measurement system was constructed to obtain the energy deposition distribution in the scintillation crystal. Subsequently, the regularization objective function is established based on weighted least squares and additional constraints. Additional constraints were designed using a special weighting scheme based on the incident gamma-ray energies. Subsequently, an intelligent algorithm was introduced to search for the optimal resolution calibration parameters by minimizing the objective function. The accurate resolution calibration parameters determined by the proposed method lay the foundation for gamma-ray spectral processing and simulation benchmarking
