Description
We report the measurement of 159Tb(n, γ) cross sections up to 1 MeV neutron energy with the TOF method at the back streaming white neutron facility of the China Spallation Neutron Source (CSNS), which is the only high intense pulsed spallation reaction neutron source in China at present. The resonance kernels of 159Tb (n, γ) are obtained up to 1.2 keV, and the MACS for the astrophysical interest energy region from kT = 5 ∼ 100 keV are calculated. The sensitivity analysis of 159Tb(n, γ)160Tb reaction rate is studied for the stellar evolution and nucleosynthesis of the 2M⊙ star model using the MESA code. We believe it will be of interest to both nuclear astrophysics and nuclear technology applications.
