核数据评价的统一耦合道和Hauser-Feshbach模型计算

Unified Coupled-Channels and Hauser-Feshbach Model Calculation for Nuclear Data Evaluation

Toshihiko Kawano

摘要:

介绍了耦合通道光学模型和Hauser-Feshbach理论计算程序CoH $_3$,重点讨论了keV到几十MeV范围内的核反应计算,并特别关注了核形变。该代码包括三个主要部分,承担的单体势平均场论,耦合通道光学模型,和豪泽-费什巴赫统计衰减。还有其他的补充部分来完成整个核反应的计算,如直接/半直接辐射俘获过程、预平衡过程和瞬发裂变中子发射。

英文摘要:

We present an overview of the coupled-channels optical model and the Hauser-Feshbach theory code CoH$_3$, which focuses on the nuclear reaction calculations in the keV to tens of MeV region with special attention to the nuclear deformation. The code consists of three major sections that undertake the one-body potential mean-field theory, the coupled-channels optical model, and the Hauser-Feshbach statistical decay. There are other complementary segments to perform the whole nuclear reaction calculations, such as the direct/semidirect radiative capture process, pre-equilibrium process, and prompt fission neutron emission.
