摘要：

The giant-resonance region of Pb208 was studied using beams of energies between 100 and 172 MeV. Relative to the excitation of the giant quadrupole resonance located at Ex=10.9 MeV the new resonance at Ex=13.8 MeV was found to be more strongly excited at higher incident energies. This yields a new piece of evidence for the monopole character of this new resonance. NUCLEAR REACTIONS Pb208(), E=100-172 MeV. Measured (E) for giant-resonance excitations. Calculated cross section for L=0 and L=2. Deduced E0 strength from energy dependence. © 1979 The American Physical Society.
