Abstract
We determine the eta-eta' mixing angle via a procedure relatively inde pendent of theoretical assumptions by simultaneously fitting eta, eta' reactions involving the anomaly eta, eta' --> gamma gamma, pi(+)pi(-) gamma. We extract reasonably precise renormalized values of the octet and singlet pseudoscalar decay constants F-8, F-0, as well as the mixi ng angle theta. [S0556-2821(98)02707-6].
