Abstract
Proceeding from the expansion of composite operators in interpolating hadronic fields, the width of the decays {eta}({eta}`) {yields}{gamma}{gamma} and J/{psi} {yields} {eta}({eta}`){gamma} have been calculated. Two mechanisms of pseudoscalar field mixing (``mass-mixing`` and ``current-mixing``) are considered. In the given schemes, the values of {eta} - {eta}`-mixing angle {theta}{sub p} are, respectively, (-15.0 {+-} 1.8) deg. and (-19.7{+-} 2.2) deg. (author). 22 refs, 1 tab.
