D. Kella et al., OBSERVATION OF LASER EXCITATION OF RHOMBIC C(4) USING THE COULOMB EXPLOSION METHOD, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 26(1-4), 1993, pp. 340-342
The combination of laser photodetachment of C4- and the Coulomb Explos
ion Imaging method was applied for the investigation of the structure
of several C4 isomers and was correlated with their measured electron
affinities.
