Abstract
The pseudoscalar, tensor, scalar and axial meson multiplets are considered in an assumption on the existence of a quark-gluon mixing. The mixing angles for these multiplets are obtained, thus allowing one to determine the quark-gluon composition of the light mesons. All the experimental data available on the two-particle decays of 0{sup -+}, 2{sup ++}, 0{sup ++} and 1{sup +{+-}}-mesons are described and predictions for a large number of such decays are given. It turned out that {eta}(1430) f{sub 2} (1720), f{sub 0} (991) and f{sub 0} (1590) mesons are quite real candidates for glueballs. f{sub 1} (1420) and f{sub 1} (1285) mesons contain almost the same 50% glueball components, this explaining many features of spectroscopy in the interval of masses from 1400 to 1500 MeV.
