Abstract：
The heavy-ion collisions are studied by means of two-component Fokker-Planck equations on the assumption that there exist multiquark states in nuclei. Inclusive cross section for the production of p is calculated in heavy-ion collisions of C+C, Ne+NaF and Ar+KCI at 800 MeV/N; Ne+NaF at 400 MeV/N, 800 MeV/N and 2100 MeV/N. A satisfactory agreement with the experimental data near c.m. 90 degree is obtained. The production of d in the collision of C+C at 800 MeV/N is also discussed.
