iThemba LABS is a home to the Separated Sector Cyclotron, which is the most powerful accelerator in the Southern Hemisphere. This cyclotron produces beams ranging from heavy to light ions up to a maximum energy of 200 MeV. The state-of-the-art K600 Magnetic Spectrometer is a unique facility world-wide for the study of nuclear structure and reaction mechanisms at intermediate energies using light-ion projectiles. In particular, high energy-resolution experiments on nuclei across the periodic table investigating the fine structure of giant resonances present a powerful tool to extract information about the dominant processes leading to equilibration. From ISGQR, IVGDR to ISGMR and in between, including recent developmental research program in maximising the capability of these unique facilities will be discussed.
