Hi Robert.
No reason not to add the missing entries. If they are not there now, it is because they probably weren’t there
when I was stealing the ion entries from your MINOS PDG table.

It looks like entirety of "rare earth elements" are missing. For 64Gd we probably need 63Eu (Europium) as final product to be defined.
