Abstract
The cross-sections for 14MeV neutron interaction with 175Lu were precisely measured by the neutron activation and off-line gamma ray technique. The neutron fluence was monitored by the accompanying α-particle of the T(d,n)α reaction, and the neutron energies were determined by using the cross-section ratio method of 90Zr(n,2n)89Zr to 93Nb(n,2n)92mNb reactions. As a result, the cross-sections of 175Lu(n,2n)174mLu, 175Lu(n,2n)174gLu, 175Lu(n,p)175m+gYb and 175Lu(n,α)172Tm reactions have been deduced at En = 14.1 ± 0.3MeV, 14.5 ± 0.3MeV and 14.7 ± 0.3MeV, respectively. Meanwhile, the comparisons between this work and the date reported by other groups previously were also given. For the comparison, it was found that there were nonnegligible discrepancies among these experimental data, as well as for several databases. As a conclusion, present data seem to be more consistent with the database of ENDF/B-VII.1, but trend to be lower than those of JEFF-3.2 and FENDL-3.1b, except the 175Lu(n,2n)174m+gLu reaction which are all in agreement.
