Semi-microscopic description of giant quadrupole resonances in deformed nuclei
Calculations of giant quadrupole isoscalar and isovector resonances in the random-phase approximation are presented. The strength functions for E2 transitions are calculated for even-even deformed nuclei in the regions of 150< or =A<190 and 228< or =A< or =248 in the 0--40 MeV energy range. The following integral characteristics of giant quadrupole resonances are obtained: position, width, contribution to the sum rule, and contribution to the total photoabsorption cross section. The calculations show that giant quadrupole resonances are a general property of all the nuclei considered. The calculated characteristics of the isoscalar giant quadrupole resonance agree with the known experimental data. The calculations demonstrate that the semi-microscopic theory can be successfully applied to the description of giant multipole resonances.
