Energy dependence of the neutron capture cross section on Zn70 near the inelastic scattering threshold

The Zn-70(n,gamma)Zn-71(m) (T-1/2 = 3.96 h) cross section has been measured at 0.40 +/- 0.15MeV and 0.70 +/- 0.10 MeV using a Li-7(p, n)Be-7 neutron source. The energy of proton energy of neutron energy spectrum code was used to calculate the neutron energy spectrum, and the (19)7Au(n,gamma)Au-198 reaction was used as monitor reaction. Detailed uncertainty analysis has been performed, and the newly measured cross sections are reported with their uncertainties and correlation coefficients. The energy dependence seen in the cross sections measured in the present work and in the previous work at higher energies has been compared with the theoretical model prediction with various level density models and gamma-ray strength functions. Model code dependence of the prediction is also discussed.
