Abstract
We present flavour-symmetric results for the OZI-allowed couplings
of
quark-antiquark systems to meson-meson channels in the
harmonic-oscillator
expansion. We tabulate their values for all possible open and
closed
decay channels of pseudoscalar, vector, and scalar mesons. We
compare
the predictions of a model that employs these flavour-symmetric
couplings, both with the results of a model which uses explicitly
flavour-dependent couplings, and with experiment.
