Abstract

The isoscalar giant monopole resonance in the nucleus ${}^{24}{Mg}$ was investigated by inelastic ${}^{6}{Li}$ scattering at $E_{Li} = 156$ MeV. At extreme forward angles fragmented $E 0$ strength was observed up to $E_{x} = 23$ MeV. The extracted strength centered at 18.3±0.5 MeV excitation energy with a width of $Γ = 4.8 \pm 0.5$ MeV corresponds to 97.3%±15% of the $E 0$ energy weighted sum rule.
