Abstract: (Elsevier)

We have calculated one-loop QCD corrections to the annihilation widths of P-wave quarkonium states into hadrons and into two photons. Comparison with accurate experimental data may lead to a clear test of perturbative QCD if α S turns out to be small enough for reasonable convergence.
