Abstract：
Time of flight counter (TOF) is one of the main subdetectors of Beijing SpectrometerII (BESII) for identification of charge particles. Time of flight and pulse amplitude are measured from the time of flight counters, when the particle hits on the TOF. Based on Di-mu sample from BESII, the correction of pulse amplitude Q is studied. Using the hadron sample of J/ψ, the relation between the corrected Pulse amplitude and βγ value is analyzed. A conclusion is that it is feasible to use the pulse amplitude Q₀ of TOF to identify the particles. Finally the efficiency and error efficiency is given while the pulse amplitude is used to identify the particles.
