Detailed investigation on the Geant4 simulation of alpha particles in liquid scintillator detector

Shiwen Xu, Shubing Liu, Zeyuan Yu

Purpose: Alpha particles from ${}^{214}$Po, ${}^{212}$Po, and ${}^{210}$Po are increasingly used to calibrate large liquid scintillator detectors, but Geant4 simulations of their energy…
