Plasma resonance profiles in the visible part of the spectrum were measured by photoabsorption spectroscopy for the clusters Na20, Na21Cl and Na22Cl2 in a beam. The resonance positions in Na20 and Na21Cl are close, suggesting that the Cl- ion does not locate at the center of the metallic droplet and does not strongly modify the effective valence electron density. The spectrum of Na22Cl2 is noticeably dissimilar to the other two, raising the possibility of structural differences and/or incomplete charge transfer.
