Rl. Neto et al., EXCITATION OF GIANT-RESONANCES IN PB-208, SN-120, ZR-90 AND NI-60 BY 84 MEV NUCLEON O-17 IONS/, Nuclear physics. A, 560(2), 1993, pp. 733-764
Elastic and inelastic scattering of 1435 MeV 170 ions on Pb-208, Sn-12
0, Zr-90 and Ni-60 have been measured. Hindrance in the excitation of
the first 3- states is observed. Parameters of the isoscalar giant mon
opole and quadrupole resonances are obtained. The quadrupole resonance
exhausts approximately 55% of the energy-weighted sum rule while the
observed monopole resonance corresponds to more than 100% of the sum r
ule. Strength is also observed at high excitation energy in all target
s.
