Abstract
We present an analysis of the K S 0K S 0 system, based on 6380 events, produced in the reactions π −p → K S 0K S 0n. Using a one-pion exchange model with absorption we determine the S- and D-wave amplitudes of ππ → K K . Several A 2 production amplitudes were also included in the fits and we conclude that an unnatural parity exchange amplitudes which does not interfere with pion exchange, seems to present. A branching ratio Γ( f → K K/ Γ( f → ππ) = 0.029 ± 0.006 is determined. With this and other new values of branching ratios we have fitted the 2 + → 0 −0 − decay rates of the SU(3) relations resulting in (36.2 ± 1)° for the tensor nonet mixing angle.
