| 英文摘要 | A measurement of the number of j/psi events collected with the besiii detector in 2009 and 2012 is performed using inclusive decays of the j/psi. the number of j/psi events taken in 2009 is recalculated to be (223.7 +/- 1.4) x 10(6), which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the besiii software. the number of j/psi events taken in 2012 is determined to be (1086.9 +/- 6.0) x 10(6). in total, the number of j/psi events collected with the besiii detector is measured to be (1310.6 +/- 7.0) x 10(6), where the uncertainty is dominated by systematic effects and the statistical uncertainty is negligible. |
