Abstract
Tho pseudoscalar mesons eta(547), eta'(958) and eta "(1410) are studied in the gluonium-quarkonium mixing framework. The SU(3)-flavor symmetry breakin g and annihilation effects are considered. Estimates of the glueball mass a nd of the m(s)/m(u) ratio are provided. The system eta(1295) and eta(1490) is also considered in a mixing scheme.
