• We present the constituent quark model for nuclear stopping in high energy nuclear collisions. It is assumed that the collided nucleons are distinguished by the number of interacted quarks and they hadronize in different ways. After examining our model in proton-nucleus collisions, it is applied to nucleus-nucleus collisions. The results for the rapidity distribution of final protons are in good agreement with the experimental data on ^<32>S + ^<32>S at E_<lab> = 200 AGeV and ^<208>Pb + ^<208>Pb at E_<lab> = 160 AGeV. Theoretical predictions are also given for proton rapidity distribution in ^<197>Au + ^<197>Au at √s = 200 AGeV (BNL-RHIC).
