摘要：

The overpopulated isoscalar tensor states are sifted using Schwinger-type mass relations. TWO solutions are found: one Where the glueball is the f(J)(2220), and one where the glueball is more distributed, with f(2)(1820) having the largest component. The f(2)(1565) and f(J)(1710) cannot be accommodated as glueball-(hybrid) meson mixtures in the absense of significant coupling to decay channels. f(2)'(1525) --> pi pi is in agreement with experiment. The f(J)(2220) decays neither flavour democratically nor is narrow.
