Abstract
The properties of the isoscalar giant monopole resonance have been studied with inelastic scattering between , where the quadrupole and monopole states can be distinguished by their angular distributions. Data were taken for , , , , , , , , , and mostly at MeV; some data were taken at MeV and MeV. A monopole resonance was identified in all the nuclei with at MeV. In nuclei with , most of the energy weighted sum rule was located in this state; in , less than one-third of the energy weighted sum rule was located. No evidence for a monopole resonance was found in nuclei with .
