  We present a study of cationic and protonated clusters of neon and krypton.
Recent studies using argon have shown that protonated rare gas clusters can
have very different magic sizes than pure, cationic clusters. Here we find that
neon behaves similarly to argon, but that the cationic krypton is more similar
to its protonated counterparts than the lighter rare gases are, sharing many of
the same magic numbers.
