“…The experimental data, generally obtained via the activation technique, are rather discrepant [cf. [10][11][12]. Since at 14 MeV the inelastic cross section of rare earth nuclei is constituted > 98% by (n, n') and (n, 2n) processes [cf.…”

Cross sections for (n, a) reactions at 14.7 ± 0.3 MeV on twentyfive stable nuclei of the elements lanthanum, cerium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and hafnium have been measured by the activation technique using high-pressure liquid chromatography and high-resolution 7-ray spectroscopy. The cross section shows a strong dependence on the relative neutron excess (N-Z)/A of the target nucleus. Hauser-Feshbach calculations show that the contributions of statistical processes to the total (n, a) cross section are small.

Abstract. The statistical model based on the Weisskopf-Ewing theory and constant nuclear temperature approximation is used for systematical analysis of the 4.0-6.5 MeV neutron induced (n, α) reaction cross sections. The α-clusterization effect was considered in the (n, α) cross sections. A certain dependence of the (n, α) cross sections on the relative neutron excess parameter of the target nuclei was observed. The systematic regularity of the (n, α) cross sections behaviour is useful to estimate the same reaction cross sections for unstable isotopes. The results of our analysis can be used for nuclear astrophysical calculations such as helium burning and possible branching in the s-process.
