We study the possibility to measure the elastic $\Phi N$ ($\Phi \equiv J/\psi, \psi(2S), \psi(3770),\chi_{2c}$) scattering cross section in the reaction $\bar p{+}d{\to}\Phi{+}n_{sp}$ and the elastic $D(\bar D) N$ scattering cross section in the reaction $\bar p{+}d \to D^- D^0 p_{sp}$. Our studies indicate that the elastic scattering cross sections can be determined for $\Phi$ momenta about 4-6 GeV/c and $D/ \bar D$ momenta 2 -- 5 GeV/c by selecting events with $p_t \geq 0.4$ GeV/c for $\Phi$'s and $p_t(p_{sp})\geq$ 0.5 GeV/c for $D/\bar D$-meson production.
