Description

The possibility of a low-energy octupole resonance in 208Pb which exhausts a significant fraction of the energy-weighted isoscalar sum rule is investigated in a distorted-wave-Born-approximation--random-phase-approximation model. It is found that the ∼15% sum-rule fraction, seen recently in low-energy (p,p') reactions, depends sensitively on the strength of the isovector projectile-target nucleon interaction
