英文摘要	Using 58 x 10(6) j/psi events collected with the beijing spectrometer (besii) at the beijing electron positron collider (bepc), the branching fractions of j/psi to p (p) over bar eta and p (p) over bar eta' are determined. the ratio gamma(j/psi -> p (p) over bar eta/gamma(j/psi -> p (p) over bar obtained by this analysis agrees with expectations based on soft-pion theorem calculations.
