A correlation theory is applied to two-sublattice antiferromagnet Cr_{2}O_{3}, for T>T_{N}. This theory includes pair correlation effects in a self-consistent calculation of both static and dynamic properties. The two kinds of approximations are assumed: the two-pole approximation for the relaxation function of the random force and the mode-mode decoupling procedure for the static and dynamic higher-order quantities. The formulae for the static susceptibility, line-shape function and magnetic cross-section of the inelastic neutron scattering are given for the case of a non-Bravais two-sublattice antiferromagnet.
