The neutron cross-section functions for the reactions 187Re(n, α) 184Ta, 187Re(n, 2n) 186Re and 185Re(n, 2n) 184Re in the energy range 13.08-19.5MeV

In the present work, measurements of the cross-section functions for the Re-187(n, alpha) Ta-184, Re-187(n, 2n) Re-186 and Re-185(n, 2n) Re-184 reactions were performed in the energy range 13.08-19.5MeV. We applied the neutron activation technique using several wide-energy neutron beams (NAXSUN), recently developed at the JRC-IRMM. This method involves measuring the activity of the radionuclides produced in a target by the in energy overlapping neutron beams and a subsequent unfolding procedure. The present results are the first experimental data on these cross-sections for incident neutron energies between 15 and 19.5MeV and may contribute to improving evaluations and nuclear models.
