Isoscalar giant resonances in (48)Ca
Abstract
The giant resonance region from 9.5 MeV < E(x) < 40 MeV in (48)Ca has been studied with inelastic scattering of 240-MeV alpha particles at small angles, including 0 degrees. 95(-15)(+11)% of E0 energy-weighted sum rule (EWSR), 83(-16)(+10)% of E2 EWSR, and 137 +/- 20% of E1 EWSR were located below E(x) = 40 MeV. A comparison of the experimental data with calculated results for the isoscalar giant monopole resonance, obtained within the mean-field-based random-phase approximation, is also given.
