Abstract

The giant-resonance region in

{}^{208}{Pb}

was observed by inelastic electron scattering. We present evidence for the existences of a

2^{+}

(or

0^{+}

) state at ∼ 22 MeV and a

3^{-}

state at ∼ 19 MeV with giant-resonance character. The resonance states between 8.6 and 11.6 MeV are confirmed to be

2^{+}

(or

0^{+}

) and the sum of their strengths exhausts about 50% of the

E 2

sum rule or 100% of

E 0

.
