Abstract
Hot CH2+ molecular ion ensembles were prepared, accelerated, and stored for radiative cooling to room temperature. The structure of the species was me asured by The Coulomb explosion imaging method at different stages of cooli ng. The bending angle distributions were extracted and compared with recent theories as well as a previous Coulomb explosion imaging measurement. The comparison reveals an apparent large nonadiabatic contribution to the low-l ying CH2+ wave functions. [S1050-2947(99)02403-8].
