Abstract
Isoscalar giant resonances in have been studied with inelastic scattering of 240 MeV α particles at small angles including . A majority of the energy weighted sum rule was identified for and (), and nearly half was identified for . The strength distributions are compared with the predictions from Hartree-Fock based random phase approximation calculations with the KDE0v1 Skyrme-type interaction. The giant monopole resonance energy moments for increase with mass, contrary to what would be expected with a negative symmetry energy, .
