Inelastic scattering at 100 MeV/u on and has been measured with the high-resolution magnetic spectrometer Grand Raiden. The magnetic-rigidity settings of the spectrometer covered excitation energies from 10 to 40 MeV and scattering angles in the range . The isoscalar giant monopole resonance was selectively excited in the present data. Measurements free of instrumental background and the very favorable resonance-to-continuum ratio of scattering allowed for precise determination of the strengths in and . Additionally, it was found that the monopole strength in exhausts of the energy-weighted sum rule (EWSR), which is considerably higher than results from previous -scattering experiments. The monopole strength in exhausts of the EWSR, and it is consistent with measurements of nuclei with mass number of . Such comparison indicates that the isoscalar giant monopole resonance distributions in these nuclei are very similar, and no influence due to nuclear structure was observed.
