abstract = {Using the once and thrice energy-weighted moments of the random-phase-approximation
strength function, we have derived compact expressions for the average energy of surface collective
oscillations of clusters and spheres of metal atoms. The L =0 volume mode has also been studied.
We have carried out quantal and semiclassical calculations for Na and Ag systems in the sphericaljellium
approximation. We present a rather thorough discussion of surface diffuseness and quantal
size effects on the resonance energies.},
