A high-resolution ({alpha},{alpha}{prime}) experiment has been performed in order to confirm the existence of the low-energy octupole resonance (LEOR) in {sup 208}Pb. Until now there was a puzzling discrepancy; an ({alpha},{alpha}{prime}) experiment denied the existence, while a ({ital p},{ital p}{prime}) measurement affirmed it. The present ({alpha},{alpha}{prime}) reaction with an improved resolution of 27 keV has identified clustering {ital L}=3 levels in the LEOR region'' in agreement with the former ({ital p},{ital p}{prime}) measurement. The observed strength, however, is weaker than the ({ital p},{ital p}{prime}) results, suggesting the coexistence of the isovector strength.
