High Energy Component of Giant Octupole Resonance in Medium and Heavy Mass Nuclei

Inelastic scattering of /sup 3/He particles at 110--140 MeV from /sup 90,92/Zr, /sup 116,118,120/Sn, /sup 144/Sm, and /sup 208/Pb nuclei exhibits the presence of a new giant resonance at E/sub x/approx.118A/sup -1/3/ MeV with a width of about 7 MeV. The angular distributions are consistent with those for L=3 transfer and octupole energy-weighted sum-rule fractions of 47--95% are exhausted for the resonance.
