Cm和Cm同位素的中子俘获反应为在核反应堆中形成更重的Cm同位素和更重的元素（如Bk和Cf）开辟了道路。此外，这两种同位素都属于次要锕系元素，对衰变热和辐照燃料中的中子发射有很大贡献，这些燃料被提议用于核废料和快临界反应堆的嬗变。这两种同位素的实验数据都非常稀少。我们用日本原子能机构提供的Cm和Cm同位素富集样品测量了中子俘获截面。该测量覆盖了n_TOF实验区域2（n-2）中从1 eV到250 eV的范围。此外，在实验区域1（X-I）用总吸收量热计（TAC）进行Cm样品的归一化测量。
The neutron capture reactions of theCm andCm isotopes open the path for the formation of heavier Cm isotopes and of heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels proposed for the transmutation of nuclear waste and fast critical reactors. The available experimental data for both isotopes are very scarce. We measured the neutron capture cross section with isotopically enriched samples ofCm andCm provided by JAEA. The measurement covers the range from 1 eV to 250 eV in the n_TOF Experimental Area 2 (EAR-2). In addition, a normalization measurement with theCm sample was performed at Experimental Area 1 (EAR-1) with the Total Absorption Calorimeter (TAC).
