Fine structure of the isoscalar giant quadrupole resonance in ²⁸Si and ²⁷Al

NUCLEAR REACTIONS ²⁷Al, Si(p, p'), E=200 MeV; measured scattered proton spectra, angular distributions using K600 magnetic spectrometer of iThemba LABS. ²⁷Al, ²⁸Si; deduced levels and resonances between 6-30 MeV excitation, isoscalar giant quadrupole resonance (ISGQR), E2 strength distributions, continuous wavelet transform (CWT) power spectra. Wavelet analysis. Comparison with random phase approximation (RPA), and second-RPA (SRPA) calculations with realistic interaction from unitary correlation operator method (UCOM). Comparison with (α, α') and (e, e') data.
