Abstract

The ²³²Th(n,2n)²³¹Th reaction cross-section was measured relative to the ⁵⁶Fe(n,p)⁵⁶Mn and ²⁷Al(n,α)²⁴Na reaction cross-sections with the activation method for neutron energies up to 11MeV. Neutrons were produced by the ²H(d,n) reaction in the 5.5MV Tandem accelerator of the NCSR "Demokritos". The characteristic γ lines of the product nuclei ²³¹Th (25.646keV) and ⁵⁶Mn (846.771keV) or ²⁴Na (1368keV) were measured with an 80mm² Si(Li) and a 20% reverse-electrode coaxial germanium detector, respectively. The results indicate that our values are in agreement with the JEF2 and BROND2 database values up to 9MeV and slightly higher than those from all the libraries for higher energies.
