Annotation
Orthopositronium production rate in the $\pi^0$-meson decay has been studied in the framework of the quasipotential method of bound state description. Relativistic and radiative corrections of the order $O(\alpha)$ to the decay width have been calculated, and their comparison with the experimental data has been carried out.
