Abstract
It is shown that vanishing of a diagonal matrix element of singlet axial current between the proton polarized states leads to a certain relation between the coupling constants of axial and pseudoscalar mesons. A connection between constants g{sub {eta}}`{sub NN}, g{sub {eta}}`{sub NN} and the {eta}`-{eta}-mixing angle has been obtained for the case when an analoque of the Goldberger-Treiman relation for the singlet axial current is valid. 26 refs.; 3 figs.
