Excitation of the giant quadrupole resonance in /sup 58/Ni with /sup 20/Ne
The heavy-ion induced excitation of the quadrupole resonance in /sup 58/Ni has been studied with /sup 20/Ne beams of 14.5 and 19.6 MeV/N incident energy. The broad resonance structure is clearly observed; the strength exhausts 44% and 60% of the energy weighted sum rule (EWSR) at the two incident en...

Sumario: | The heavy-ion induced excitation of the quadrupole resonance in /sup 58/Ni has been studied with /sup 20/Ne beams of 14.5 and 19.6 MeV/N incident energy. The broad resonance structure is clearly observed; the strength exhausts 44% and 60% of the energy weighted sum rule (EWSR) at the two incident energies, respectively. The background is partly explained by a three-body reaction mechanism, which is based on the one-nucleon pick-up reaction into unbound states followed by one- nucleon emission. The remaining part is interpreted as inelastic excitation of other multipoles. (11 refs). |
