Evaluation of neutron induced reaction cross sections on Re isotopes

Iwamoto, Nobuyuki  

Neutron nuclear data on Re isotopes are not included in the latest version of JENDL-4.0. Radioactive nuclides, which could become important to nuclear medicine, were produced by nuclear reaction on stable Re isotopes. In this work neutron induced reaction cross sections on Re isotopes (Re) were evaluated by using nuclear reaction calculation code CCONE. The incident energy range was considered from 10 eV to 20 MeV, whose range included the resolved resonance region. The evaluation was made by comparing the calculated results with available experimental data of the total, elastic scattering, capture, (n,2n), (n,p), (n,) reaction cross sections on Re and elemental Re. The present results well explain the experimental data. The capture cross sections on Re isotopes are important to consider the Re-Os cosmochronology. Maxwellian averaged capture cross sections were also derived and compared with the data of KADoNiS database.
