摘要：

Several processes of meson production in proton-deuteron collisions have been measured simultaneously using a calibrated magnetic spectrograph. Among these processes, the eta meson is seen clearly as a sharp missing-mass peak on a slowly varying background in the p + d -> He-3 + X reaction. Knowing the kinematics of the other reactions with well determined masses, it is possible to deduce a precise mass for the eta meson. The final result, m(eta) = 547.311 +/- 0.028(stat) 0.032(syst) MeV/c(2), is significantly lower than that found by the recent NA48 measurement, though it is consistent with values obtained in earlier counter experiments.
