Abstract
The Hauser-Feshbach codes, EMPIRE, TALYS, CCONE, and CoH3 , which are widely utilized in nuclear data evaluations, are compared, with a particular focus on neutron-induced reactions on major actinides. We report the results of Hauser-Feshbach calculations using well-defined input parameters, and discuss the differences among these codes.
Highlights
The Hauser-Feshbach (HF) codes that include a preequilibrium model have been playing for years a central role in producing evaluated nuclear reaction data files
The codes, such as EMPIRE [1], TALYS [2], CCONE [3], and CoH3 [4], have been and are still actively upgraded in order to better understand nuclear reaction mechanisms by sharing and exchanging theoretical knowledge as well as computational techniques among actors involved in their development
The International Atomic Energy Agency (IAEA) Nuclear Data Section conducts one of such interorganizational collaborations, and defined some exercises to compare the HF codes developed for nuclear data evaluations, with a particular focus on the actinide evaluations
Summary
The Hauser-Feshbach (HF) codes that include a preequilibrium model have been playing for years a central role in producing evaluated nuclear reaction data files. The codes, such as EMPIRE [1], TALYS [2], CCONE [3], and CoH3 [4], have been and are still actively upgraded in order to better understand nuclear reaction mechanisms by sharing and exchanging theoretical knowledge as well as computational techniques among actors involved in their development. Albeit the framework of the model codes aforementioned is quite similar, implementation of the reaction models as well as computational techniques adopted may produce some differences in the calculated results. In this paper we report the results of HF calculations for neutron induced reactions on 238U and 239Pu employing the input parameters defined in the IAEA report [6]
