A high-resolution experiment has been performed in order to confirm the existence of the low-energy octupole resonance (LEOR) in Pb208. Until now there was a puzzling discrepancy; an experiment denied the existence, while a (p,p) measurement affirmed it. The present reaction with an improved resolution of 27 keV has identified clustering L=3 levels in the LEOR regionin agreement with the former (p,p) measurement. The observed strength, however, is weaker than the (p,p) results, suggesting the coexistence of the isovector strength.
