چکیده
In this paper, a data-driven method to precisely simulate the detector response of anti-neutron depositing in Electromagnetic Calorimeter (EMC)at BESIII is introduced. A large data sample can be selected using decay $J/\psi\to p\bar{n}\pi^{-}$ from 10 billion $J/\psi$ events. The detection efficiency for and various observables anti-neutrons interacting EMC are simulated, taking correlations among variables into consideration. systematic uncertainty simulation determined less than 1\% on average. This widely applied physics processes that require precise EMC.
