Cross-section Measurements of (n,xn) Threshold Reactions

Popis výsledku v původním jazyce

There are significant voids in the cross-section libraries of (n,xn) reactions in many materials. This was realized during the "Energy plus Transmutation" project, at which Au, Al, Bi, In and Ta activation detectors were used to measure high-energy neutrons produced in spallation reactions. Threshold (n,alpha), (n,p) and (n,xn) reactions were observed with the x up to 9 (threshold ~90 MeV), but almost no experimental cross-section data are available for neutron energies above 20 MeV. Seven successful irradiations were performed last year on quasi-monoenergetic neutron sources based on the 7Li(p,n)7Be reaction. The (n,alpha), (n,p) and (n,xn) cross-sections on Al, Au, Bi, In, I, and Ta were measured in the experiment at TSL in Uppsala at neutron energies 22, 47, and 95 MeV. Further four irradiations were done at NPI in Řež with the neutron beams of 17, 22, 30 and 35 MeV.
