Measurements of the cross section for the 182W(n,p)182(m+g)Ta and 184(n,p)184Ta reactions in the 14Â MeV energy range using the activation technique

The cross section for the 182W(n,p)182(m+g)Ta and 184W(n,p)184Ta reactions has been measured in the neutron energy range of 13.5-14.7 MeV using the activation technique and a coaxial HPGe γ-ray detector. In our experiment, the fast neutrons were produced by the T(d,n)4He reaction at the ZF-300-II Intense Neutron Generator at Lanzhou University. Natural wolfram foils of 99.9% purity were used as target materials. The neutron flux was determined using the monitor reaction 93Nb(n,2n)92mNb and the neutron energies were determined using the method of cross-section ratio measurements employing the 90Zr(n,2n)89Zr to 93Nb(n,2n)92mNb reactions. The results of this work are compared with experimental data found in the literature and the estimates obtained from a published empirical formula based on the statistical model with Q-value dependence and odd-even effects taken into consideration.
