Description

Using the nonmagnetic BONANZA detector for the detection of antineutrons and antiprotons, we measured branching ratios of the J/psi into baryonic final states. Our measurements give the new results: BR(J/psi → anti Σ-Σ-) = (0.24 +- 0.26)%; BR(J/psi → anti nnπ+π-) = (0.38 +- 0.36)% and an independent test for the data of the magnetic detectors. (orig.)
