Joint Evaluated Fission and Fusion File

The Joint Evaluated Fission and Fusion File (JEFF) project is a collaboration between NEA Data Bank member countries. The JEFF library combines the efforts of the JEFF and EFF/EAF Working Groups to produce a common sets of evaluated nuclear data, mainly for fission and fusion applications. It contains a number of different data types, including neutron and proton interaction data, radioactive decay data, fission yields, and thermal scattering law data

联合核裂变与核聚变评估文件（JEFF）项目是由国际原子能机构（NEA）数据银行成员国共同发起的一项合作项目。JEFF库汇集了JEFF和EFF/EAF工作组的工作成果，旨在生成一套通用的评估核数据集，主要用于核裂变和核聚变应用。该库包含了多种不同的数据类型，包括中子和质子相互作用数据、放射性衰变数据、裂变产额数据以及热散射定律数据。
