Abstract

Assuming that the dominant mechanism for high-energy meson-nucleon charge-exchange scattering is the exchange of

I = 1

members of

SU (3)

octet meson states, the sum rule

\frac{d σ}{dt} (K^{-} p \to {\bar{K}}^{0} n) + \frac{d σ}{dt} (K^{+} n \to K^{0} p) = \frac{d σ}{dt} (π^{-} p \to π^{0} n) + 3 \frac{d σ}{dt} (π^{-} p \to η n)

is derived and discussed.
