  The results of calculations of the muon transfer rate from the 1S state of
muonic hydrogen to the nucleus of a free oxygen atom are presented in the
interval of collision energies from 10^(-4) to 10 eV. The calculations were
performed within a version of the perturbed stationary states method proposed
earlier. The electron screening in the entrance channel of the transfer
reaction was taken into account. A p-wave resonance in the transfer rate is
predicted at collision energies of about 0.1 eV. This result is of interest in
the context of the planned laser experiment on precise measurements of the
hyperfine splitting energy of the 1S state of muonic hydrogen.
