Description
The shape transition of the Isovector Giant Dipole Resonance (IVGDR) from the spherical 142Nd to the deformed 150Nd nuclei in the even-even 142-150Nd chain has been established using proton inelastic scattering at zero degrees. Comparisons were made to previous photo-absorption results and some discrepancies were found which have implications for astrophysical applications (PLB in preparation). In addition, 152Sm was measured to allow for comparisons to its isotone, 150Nd, to be made. These results will be discussed along with the proposal to perform a coincidence measurement of the IVGDR in 154Sm via proton inelastic scattering and the observation of the subsequent γ-ray decays with BaGeL (Bagel Array of Ge and LaBr detectors). The 154Sm data in addition to 150Sm and 152Sm data from a previous experiment will provide insight into the transition region of the samarium isotope chain and will provide an opportunity to test the equivalent virtual photon method in this region.
