Calculations indicate that all these are joined via a cycloaddition (at least in the neutral state), and in fact so are the C 60 cages in all solid-state polymer phases characterized so far. The C 60 dimer that has recently been synthesized and isolated by chemical means is also a cycloadduct. shepherds and angels in the field
