Yield estimation of neutron-rich rare isotopes induced by 200 MeV/u 132 Sn beams by using GEANT4

Abstract

a b s t r a c tA 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 132 Sn beams bombarded on a 9 Be 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 59 Co, 95 MeV/u 72 Zn, 500 MeV/u 92 Mo, and 950 MeV/u 132 Sn beams on the 9 Be target. It is found that 132 Sn beams can produce neutron-rich rare isotopes with 45 6 Z 6 50 more effectively than 238 U beams at the same energy per nucleon.

Status of the RAON project in Korea

“…In the absence of SCL1, the stable ion beams from the ECR ion sources or RIBs from the ISOL system are transported and accelerated by the injector system and the SCL3. Possible RIB generation and acceleration methods can be summarized as follows: [4].…”

A data-based photonuclear reaction model for GEANT4

“…It has been thoroughly tested and is being widely used in many different scientific fields, such as medical physics [32][33][34], accelerator-based radiation studies [35][36][37][38], neutron shielding studies [39][40][41], environmental radiation detection studies [42][43][44][45], etc. Additional information, validations and detailed descriptions of the GEANT4 can be found on the GEANT4 website [46].…”

Overview of the Rare isotope Accelerator complex for ON-line experiments (RAON) project

“…Ultimately, RAON will attempt to use RIBs from the ISOL system to produce more neutron-rich ion beams by bombarding them to the IF target. The simulations have shown that the combination of ISOL and IF can produce new RIB species near the neutron dripline or enhance the yields of certain rare isotopes by large factors [5].…”
