A so-called "two-step reaction scheme", in which neutron-rich rare isotopes obtained from ISOL are post-accelerated and bombarded on a second target, is employed to estimate the production yields of exotic rare isotopes. The production yields of neutron-rich rare isotope fragments induced by 200 MeV/u 132Sn beams bombarded on a 9Be target are estimated with Monte Carlo code, GEANT4. To substantiate the use of GEANT4 for this study, benchmark calculations are done for 80 MeV/u 59Co, 95 MeV/u 72Zn, 500 MeV/u 92Mo, and 950 MeV/u 132Sn beams on the 9Be target. It is found that 132Sn beams can produce neutron-rich rare isotopes with 45 ≤ Z ≤ 50 more effectively than 238U beams at the same energy per nucleon.
