摘要：

The isoscalar giant quadrupole resonance in Si-28 and Al-27 has been investigated with high-energy-resolution proton inelastic scattering at E-p = 200 MeV and at scattering angles close to the maximum of Delta L = 2 angular distributions with the K600 magnetic spectrometer of iThemba LABS, South Africa. Characteristic scales are extracted from the observed fine structure with a wavelet analysis and compared for Si-28 with random-phase approximation and second random phase approximation calculations with an interaction derived from the Argonne V18 potential by a unitary transformation. A recent extension of the method to deformed nuclei provides the best description of the data, suggesting the significance of Landau damping.
