摘要：
The decays of tenser mesons into two pseudoscalars mesons and into a vector meson and a pseudoscalar meson have been used for a SU(3) analysis of the tenser nonet. We find compatibility of all tenser decay branching ratios with SU(3) relations assuming no suppression of s $$($) over bar s pair creation. If a possible s $$($) over bar s suppression is parameterized by one factor lambda, it is found to be lambda = 0.8 +/- 0.2. In addition, the pseudoscalar mixing angle is determined to -(15 +/- 3)degrees.
