$Limitations on the chiral coupling constants of the weak hadronic neutral current are inferred from data (~ 13 000 events) obtained by bombarding the 15-foot Fermilab bubble chamber with a wide-band beam of antineutrinos. The squares of the right constants are found with the help of the left constants from neutrino experiments to be <i>u\ </i>= 0.033 + 0.017 and <i>d % </i>= 0.002 ± 0.017.$
