Activation of material is of interest for waste treatment and hazard assessment. In particular, activation of printed circuit can lead to the production of radionuclides at an isomeric state, for example, coming from silver. In particle accelerators, the production of silver isomeric states mainly come from low energy neutrons, below 20 MeV. The quantification of activation and associated doses at CERN is based on the FLUKA and ActiWiz codes. In the FLUKA release 2011.2c, all branching ratios for isomer production were set at 50% by default. The present work provides a set of nuclide- and energy-dependent branching ratios, extracted from the library EAF-2010. In the ActiWiz release 3.3, the library JEFF3.1.1 was used for low energy neutron cross-sections. This study provides a new set of neutron cross-sections extracted from JEFF3.3, ENDFB/VIII.0 and EAF-2010 for future update of ActiWiz.

材料的激活对于废物处理和危害评估很重要。特别地，印刷电路的激活可以导致以例如来自银的异构态产生放射性核素。在粒子加速器中，银异构态的产生主要来自低于20 MeV的低能中子。CERN的激活剂量和相关剂量的定量基于FLUKA和ActiWiz代码。在FLUKA版本2011.2c中，默认情况下，异构体生产的所有支化比率均设置为50％。本工作提供了一组从核素和能量依赖的分支比率，该比率从EAF-2010库中提取。在ActiWiz版本3.3中，库JEFF3.1.1用于低能中子截面。这项研究提供了从JEFF3.3，ENDFB / VIII中提取的一组新的中子截面。
