Doubly charged CO2 clusters formed by ionization of doped helium nanodroplets☆
•Doubly charged CO2 clusters are fingerprinted by detecting their isotopologues.•Contributions from singly charged ions are eliminated by background subtraction.•Smaller doubly charged ions than reported so far are identified.•A sequential process that involves Penning ionization is invoked to expla...
