A systematic experimental investigation was performed of the phenomenon associated with the fine structure of giant resonances, with emphasis on the Isoscalar Giant Monopole Resonance (ISGMR), for 208Pb, 90Zr, 58Ni and 40Ca using a 200 MeV alpha-particle beam delivered by the Separated Sector Cyclotron of iThemba LABS. These nuclei are of special interest since they are doubly-magic, 208Pb and 40Ca, and proton-magic, 90Zr and 58Ni. Measurements were made using the state-of-the-art K = 600 magnetic spectrometer to obtain unique high energy-resolution alpha-particle inelastic scattering excitation-energy spectra in the region of ISGMR at θlab = 0° where the cross-section of the ISGMR is at a maximum. In addition, measurements were also made for all four target nuclei at θlab = 4°, where the cross-section of the Isoscalar Giant Quadrupole Resonance (ISGQR) is at a maximum. This was done in order to subtract the contribution of the ISGQR from the excitation energy spectra taken at zero degrees. Preliminary results are presented.
