Nuclear-Structure Experiments at iThemba LABS to Investigate Discrepancies Between (p, p') and (*g, xn) Data / L.M.Donaldson, W.Kleinig, V.O.Nesterenko, [a.o.] // 28th International Nuclear Physics Conference (INPC 2022), Cape Town, South Africa, 11-16 September 2022 [Electronic resource]. – Bristol : IOP Publishing, 2023. – P.012068. – URL: https://doi.org/10.1088/1742-6596/2586/1/012068. – Bibliogr.:39.

The iThemba Laboratory for Accelerator Based Sciences (iThemba LABS) is a centre of expertise and innovation in the field of nuclear-structure physics and is a leader in several high-impact studies. One of the highlights of these nuclear-structure experiments is the study of the broad structure of the IsoVector Giant Dipole Resonance (IVGDR) in the rare-earth region. Proton inelastic scattering experiments with Ep = 200 MeV were performed on the even-even Nd isotope chain and 152Sm at very forward scattering angles including zero degrees with the K600 magnetic spectrometer. The evolution of the shape of the IVGDR in the transition from spherical to deformed nuclei was investigated. One of the goals of this highlighted study was to confirm the K-splitting observed in previous photo-absorption measurements from Saclay. Significant discrepancies were found between the direct (γ, xn) data obtained at Saclay and the equivalent photo-absorption cross sections obtained using (p, p') data from the K600. Furthermore, discrepancies exist for several nuclei between photo-absorption data taken at the Saclay and Livermore laboratories. These discrepancies, possible reasons for them and future investigations will be presented and discussed. – (Journal of Physics: Conference Series ; Vol.2586) .
