| 中文摘要 | Using Monte Carlo simulation, reconstruction of photon conversions is studied, and the detection efficiency and energy resolution as a function of photon energy are obtained. The dE/dx correction for the electrons from photon conversions and the energy scale for the photons are calibrated with BES II data. An improved Crystal Ball function describes well the energy distribution of the photons. Photon energy resolutions in the range from 2.3 to 3.8MeV are found for the photons with energy from 100 to 260MeV at the BES II detector. |
