Description
The shape transition of the IsoVector Giant Dipole Resonance from the spherical $^{142}$Nd to the deformed $^{150}$Nd nuclei in the even-even $^{142−150}$Nd chain was established using proton inelastic scattering at zero degrees with the K600 Magnetic Spectrometer at iThemba LABS. The effect of deformation on the broad and the fine structure of the IVGDR was investigated. Comparisons were made to previous photo-absorption results obtained at Saclay and significant discrepancies that have implications for several applications were found. In addition to this, discrepancies between photo-absorption data from the Saclay and Livermore laboratories have been found for several nuclei. The Nd results, observed discrepancies, possible reasons for them and future investigations will be presented and discussed.
