Description

The last few decades have proved to be quite exciting in the field of nuclear structure physics.High energy-resolution proton inelastic-scattering experiments revealed that giant resonances carry fine structure as a signature of the damping mechanisms involved. For the first time itis now possible to achieve such high energy-resolution measurements with intermediate energy (specifically 200 MeV) alpha-particle inelastic-scattering reactions at zero degrees. The choice of scattering angle as well as the projectile was motivated for as together they achieve the preferential excitation of the Isoscalar Giant Monopole Resonance (ISGMR). As part of the longstanding WITS/IKP Darmstadt/iThemba collaborative program on the investigation of properties of Nuclear Giant Resonances, these experiments have been performed using the Separated Sector Cyclotron (SSC) at the iThemba LABS and the K600 magnetic spectrometer for a range of nuclei including 24 Mg, 58 Ni and 90 Zr. Preliminary results will be presented.
