The new rare isotope accelerator RAON, which is under construction in Korea, will provide opportunities to perform heavy-ion collision experiments. $^{132}$Sn and $^{140}$Xe are among the major sources of projectiles at RAON. These isotopes are important sources for investigating nucleosynthesis in the Universe and the nuclear symmetry energy. In this work, we did a computer simulation of $^{132}$Sn$+^{208}$Pb and $^{140}$Xe$+^{208}$Pb collision experiments with a given beam energy at $E_{\rm lab}$ = 200 MeV/u. In the computer simulation, we use relativistic mean field theory to describe the dense nuclear matter and RBUU (Relativistic Boltzmann-Uehling-Uhlenbeck) transport model to describe the nuclear collisions. We found that the temperature at the center of the colliding system reached $\sim$30 MeV, and study the possibilities of various low-energy nuclear matter phase transitions.
