The properties of the isoscalar giant monopole resonance have been studied with inelastic ..cap alpha.. scattering between 0/sup 0/< or =q/sub L/< or =8/sup 0/, where the quadrupole and monopole states can be distinguished by their angular distributions. Data were taken for /sup 12/C, /sup 27/Al, /sup 40/Ca, /sup 48/Ti, /sup 58/Ni, /sup 64,66/Zn, /sup 90/Zr, /sup 116,118,120,124/Sn, /sup 144,154/Sm, and /sup 208/Pb mostly at E/sub a/ = 129 MeV; some data were taken at E/sub a/ = 99 MeV and E/sub a/ = 117 MeV. A monopole resonance was identified in all the nuclei with A> or =64 at E/sub x/roughly-equal76/A/sup 1/3/ MeV. In nuclei with A> or =90, most of the energy weighted sum rule was located in this state; in /sup 64,66/Zn, less than one-third of the energy weighted sum rule was located. No evidence for a monopole resonance was found in nuclei with A< or =58.
