Short-range correlations (SRC) in asymmetric nuclei with an unusualneutron-to-proton ratio can be studied with quasi-free two-nucleon knockoutprocesses following the collision between accelerated ions and a proton target.We derive an approximate factorized cross section for those SRC-driven$p(A,p^{\prime} N_1 N_2)$ reactions. Our reaction model hinges on thefactorization properties of SRC-driven $A(e, e^\prime N_1 N_2)$ reactions forwhich strong indications are found in theory-experiment comparisons. In orderto put our model to the test we compare its predictions with results of$^{12}\text{C}(p,p^{\prime} pn)$ measurements conducted at Brookhaven NationalLaboratory (BNL) and find a fair agreement. The model can also reproducecharacteristic features of SRC-driven two-nucleon knockout reactions, likeback-to-back emission of the correlated nucleons. We study the asymmetrydependence of nuclear SRC by providing predictions for the ratio ofproton-proton to proton-neutron knockout cross sections for the carbon isotopes$^{9-15}$C thereby covering neutron excess values $(N-Z)/Z$ between -0.5 and+0.5.
