|Abstract:||Resonance energies Eλ, neutron widths Tn,λ, and radiation widths Tγ ,λ for the compound system 175Lu + n were determined up to 1 keV from time-of-flight data reported in literature and recently measured at the GELINA facility of JRC-Geel (Belgium). The statistical analysis of the obtained resonance parameters provides an swave neutron strength function [S0 = 1.96(8)], mean level spacing [D0 = 3.24(9) eV], and average radiation width (<Tγ0> = 61.3(59) meV) which are substantially different from those compiled in libraries dedicated to statistical calculations. The largest difference lies on the average radiation width, for which a value of 77(5) meV is recommended. 175Lu neutron cross sections were calculated with the TALYS code by using our s-wave average parameters as constraints. At kT = 30 keV, we obtain a total neutron capture cross section equal to 1125(62) mbarns, confirming the lower values reported in the 1990s.|
