63Cu (n, γ) cross section measured via 25 keV activation and time of flight

NUCLEAR REACTIONS 63Cu(n, γ), E=75 eV to 500 keV; measured Eγ, Iγ, time of flight, σ(E) by activation with a quasistellar neutron spectrum at JRC-Geel, and the energy dependence of the cross section measured with an isotopically enriched 63Cu sample placed in the center of the DANCE detector array at LANSCE-LANL facility; deduced Maxwellian-averaged cross sections for the whole temperature range relevant for different scenarios of the s-process nucleosynthesis. Comparison with previous experimental measurements and with evaluated cross sections from TENDL-2015.
