Properties of the tensor mesons f(2)(1270) and f(2)'(1525)

In the f(2)(1270)-f ' (2)(1525) mixing framework, the isoscalar singlet-oct et mixing angle for the 1 P-3(2) tenser nonet is determined to have the val ue of 27.5 degrees and the decays of the two states are investigated. Compa ring the predicted results of the decays of the two states with the availab le experimental data, we find that the predicted results based on this simp le mixing picture are in good agreement with the experimental data, which s how that the f(2)(1270) and f ' (2)(1525) wavefunctions do not need other c omponents such as glueballs or the 2 P-3(2), 3 P-3(2),..., q (q) over bar.
