Measurements of NeD/sup +/ dissociative excitation cross section were obtained in Louvain-la-Neuve (UCL, Belgium) by using the animated crossed electron-ion beam method. The electronic structure of the system was calculated by using quantum chemistry calculations for the NeD/sup +/ ion and ab initio electron scattering calculations using the complex Kohn variational method for the resonant NeD neutral complex formed by the temporary capture of the electron by the ion. The cross section for dissociative excitation are then calculated below the second excitation thresholds of the ion where the process is dominated by a series of doubly-excited resonance states. Theory and experiment are then compared.
