The Kawai model describing the glueball-quarkonia mixing is modified. The m
ixing of eta, eta' and eta(1410) is re-investigated based on the modified K
awai model. The glueball-quarkonia content of the three states is determine
d from a Bt to the data of the electromagnetic decays involving eta, eta'.
Some predictions about the electromagnetic decays involving eta(1410) are p
resented.
