Description
iThemba LABS, South Africa, is a suitable laboratory for the experimental study of giant and
pygmy resonances. The K600 magnetic spectrometer is one of the few spectrometers in the
region of 30-200 MeV with high-energy resolution and the ability to perform measurements at
zero degrees. This capability enabled the study of the fines structure in giant resonances and the
role of deformation in these collective modes. In addition, the recent developments of
coincidence measurements of charged particle and γ-ray decays is a perfect combination to
investigate the nature of the pygmy dipole resonance and in general broad excited structures in
detail.
Results on the experiments conducted at iThemba LABS on giant and pygmy resonances will be
shown.
