Thresholds for the Break of Nucleon Cooper Pairs and Special Features of the Decay of the 172Yb Nucleus in the Reaction 171Yb(nth,2γ)

Physics of Atomic Nuclei volume 81, pages 296–306 (2018)Cite this article

Abstract

The reaction 171Yb(nth,2γ) was studied with the aim of extending the experimental database of intensities of cascades of two photons emitted sequentially after radiative thermal-neutron capture. An analysis of these cascade intensities permitted revealing the change in the structure of observed levels of the 172Yb nucleus versus the excitation energy and determining probable thresholds for the break of four Cooper pairs of neutrons below the neutron binding energy.
