Resumo
Exotic nuclei cross sections data became crucial for the nuclei formation study existing in nature and for the
reactors engineering. These data are currently determined in experiment realized in post-accelerator or high
intensity neutron sources. So, in IPEN is being studied an experiment to calculate the neutron-rich nuclei cross
section using the IEA-R1 reactor. The first step is to development software in GEANT4 to determine 140Ba
quantities when a Uranium sample is irradiated. 140Ba is an interest element in nuclear astrophysics with halflive
sufficient to be detected in Uranium fission chain within nuclear reactors. The GEANT4 Detector
Construction class is the class where the Uranium sample and neutron source are localized and the Physics and
Process class determine the neutron source beam characteristics. Two tests were performed with different
neutron quantities in the irradiated beam which is directed to a Uranium sample, with 20% of U235 and 80% of
U238, in box shape. For the first test were produced 121 nuclei. And, for the second test was produced 3568
nuclei, being a value reasonable to detect in the experiment.
