对锌的五种稳定同位素（质量数A = 64、66、67、68和70）的中子感生核数据的新评估在入射中子能量从10−5 eV到20 MeV的范围内持续进行。在低能区，约100keV，共振参数进行了评估，考虑到现有的测量数据。在快中子区，采用考虑了复合、预平衡和直接过程的核反应模型，进行了综合计算，估算了各种反应的截面以及发射中子和γ射线的双微分截面。将计算截面与实验数据和现有的核数据库进行了比较，结果表明计算截面与测量结果吻合较好。
New evaluation of neutron-induced nuclear data for five stable isotopes of zinc (mass numbers A = 64, 66, 67, 68, and 70) was consistently carried out in the incident neutron energy range from 10−5 eV up to 20MeV. In the low energy region up to about 100keV, the resonance parameters were evaluated by taking account of the available measured data. In the fast neutron region, the comprehensive calculations with nuclear reaction models, in which compound, preequilibrium, and direct processes are taken into account, were performed to estimate cross sections for various reactions and double differential cross sections of emitted neutrons and γ-rays. The comparisons of the evaluated cross sections with the experimental data and existing evaluated nuclear data libraries are made and show a good agreement with the measurements.
