We report on a study of diffractive dijet production in $/bar{p}p$ collisions at $/sqrt{s}=1.96$ TeV using the CDF II detector at the Fermilab Tevatron $/bar{p}p$ collider. A data sample from 310 pb$^{-1}$ of integrated luminosity collected by triggering on a high transverse energy jet. Results are presented for the region of $/bar p$-momentum-loss fraction $0.03</xi_{/bar p}<0.09$ and a four-momentum transfer squared $t_{/bar p}>-4$ GeV$^2$. The $t_{/bar p}$ dependence is measured as a function of $Q^2$ and $x_{Bj}^{/bar p}$ and compared with that of inclusive single diffraction dissociation. We find weak $x^{/bar p}_{Bj}$ and $Q^2$ dependencies in the ratio of single diffractive to inclusive event rates, and no significant $Q^2$ dependence in the diffractive $t_{/bar p}$ distributions.
