Abstract
A recent Letter reports photoemission data for the free C60 molecule, showing an interesting three-peak structure, presented as evidence of dynamic Jahn-Teller (DJT) effect in the C60+ ion. Those data constitute, along with earlier spectra by the Uppsala group, the best available piece of experimental evidence about the spectrum of a hole in fullerene. DJT must indeed affect the fivefold-degenerate h_u hole molecular orbital, but we contend that the energy separation of these three peaks is far too large for the proposed tunneling interpretation to be correct.
