Abstract

Six independent combinations of cross-section data involving meson-nucleon charge-exchange amplitudes at the forward direction are analyzed in terms of

ρ

(

J^{P} = 1^{-}

I^{G} = 1^{+}

) and

A

(

J^{P} = 2^{+}

I^{G} = 1^{-}

) Regge-exchange model. SU(3) tests for the ratios of the Regge-pole residues give

\frac{γ_{ρ \bar{K} K}}{γ_{ρ π π}} = 1.12 \pm 0.12

and

\frac{γ_{A \bar{K} K}}{γ_{A π η}} = 1.07 \pm 0.15

, consistent with exact symmetry values of 1.
