- ItemEvolution of the IVGDR and its fine structure from doubly-magic 40⁴°Ca to neutron-rich ⁴⁸Ca probed Using (p,p′) scattering(Jagellonian University, 2019) Latif, M. B.; Usman, I. T.; Carter, J.; Sideras-Haddad, E.; Donaldson, L .M.; Jingo, M.; Kureba, C. O.; Pellegri, L.Experiments investigating the fine structure of the Isovector Giant Dipole Resonances (IVGDR) have been carried out on target nuclei 40,42,44,48Ca with 200 MeV proton inelastic scattering reactions using the high-energy resolution capability and the zero-degree set-up at the K600 magnetic spectrometer of the iThemba LABS, Cape Town, South Africa. Quasi-free scattering background contributions in the experimental data have been removed by applying a novel method of Discrete Wavelet Transform (DWT) analysis. Energy scales extracted are compared with the state-of-the-art theoretical calculations within the framework of the Quasiparticle-RPA and Relativistic Quasiparticle Time Blocking Approximation (RQTBA). For 40,48Ca, these calculations consider all major processes (Landau damping, escape width, spreading width) contributing to the damping of the IVGDR.
