Description

The fine structure of the low-energy octupole resonance was studied for 48Ca, 90Zr, and 208Pb by proton inelastic scattering at E/sub p/ = 65 MeV. The low-energy octupole resonance was composed of many discrete levels of L = 3 states. The total energy-weighted sum rule fraction of more than 10% was found in every nucleus. Especially in 208Pb, the energy-weighted sum rule fraction amounted to 15%. The strength was finely fragmented in 90Zr, but less fragmented in 208Pb. It is suggested that the ''degree of fragmentation'' is correlated with the excitation energy and the distribution of the low-lying quadrupole phonon states
