Description
The neutron capture reactions in 244Cm and 246Cm isotopes open the path of the formation of heavier Cm isotopes and heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes are two of the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels proposed for the transmutation of the nuclear waste and fast critical reactors. The available experimental data for both isotopes is very scarce due to the difficulties in performing the measurements: high intrinsic activity of the samples and the limited facilities capable of providing isotopically enriched samples. We measure the neutron capture cross section measurement with isotopically enriched samples of 244Cm and 246Cm provided by JAEA. The measurement covers the range from 1 eV to 250 eV. The measure was done in to difference experimental areas with different detectors: In Experimental Area 2 (EAR-2) with C6D6 and also in experimental Area 1 (EAR-1) with the Total Absorption Calorimeter.
