摘要原文
Fluctuations in photon production in the scintillator could contribute to the total energy resolution of the scintillation detector. The contribution, called intrinsic resolution (IR), is one of the factors limiting the total energy resolution in detectors based on liquid organic scintillators (LSs). There are very few experimental measurements of IR in LSs available, and the underlying physics is not completely understood. We propose a phenomenological description of the IR of LSs and systematize the data available using a single universal parameter characterizing the IR. We show that within the frames of the model, all experimental data demonstrate the presence of extra smearing of energy resolution due to the IR with a typical value of $\simeq2$\% at 1 MeV energy release. The model can be used to simulate the effect of IR in LS-based detectors.
