| Zusammenfassung: | <jats:p>Nowadays, there is an increased interest in a complete study of the neutron-induced fission of <jats:sup>237</jats:sup>Np. This is due to the need of accurate and reliable nuclear data for nuclear science and technology. <jats:sup>237</jats:sup>Np is generated (and accumulated) in the nuclear reactor core during reactor operation. As one of the most abundant long-lived isotopes in spent fuel (“waste”), the incineration of <jats:sup>237</jats:sup>Np becomes an important issue. One scenario for burning of <jats:sup>237</jats:sup>Np and other radio-toxic minor actinides suggests they are to be mixed into the fuel of future fast-neutron reactors, employing the so-called transmutation and partitioning technology. For testing present fission models, which are at the basis of new generation nuclear reactor developments, highly accurate and detailed neutron-induced nuclear reaction data is needed. However, the EXFOR nuclear database for <jats:sup>237</jats:sup>Np on neutron-induced capture cross-section, σ<jats:sub>γ</jats:sub>, and fission cross-section, σ<jats:sub>f</jats:sub>, as well as on the characteristics of capture and fission resonance parameters (Γ<jats:sub>γ</jats:sub>, Γ<jats:sub>f</jats:sub>, σ<jats:sub>o</jats:sub>Γ<jats:sub>f</jats:sub>, fragments mass-energy yield distributions, multiplicities of neutrons v<jats:sub>n</jats:sub> and γ-rays v<jats:sub>γ</jats:sub>), has not been updated for decades.</jats:p> |
