Abstract
The isoscalar giant resonance region has been investigated in $^{58}\mathrm{Ni}$, $^{92}\mathrm{Mo}$, and $^{120}\mathrm{Sn}$ nuclei by inelastic scattering of $^{4}\mathrm{He}$ particles at small angles where the quadrupole and monopole states can be distinguished through their angular distributions. A monopole resonance is observed in the three nuclei, exhausting, respectively, 23%, 85%, and 110% of the E0 energy weighted sum rule.
