Coulomb-explosion imaging of CH{sub 2}{sup +}: Target-polarization effects and bond-angle distribution

The effect of target polarization fields on the bond-angle distribution following the foil-induced Coulomb explosion of CH{sub 2}{sup +} has been measured. Incorporating a detailed model description of the polarization effects and other target effects into a Monte Carlo simulation of the experiment,...

Description
Summary:The effect of target polarization fields on the bond-angle distribution following the foil-induced Coulomb explosion of CH{sub 2}{sup +} has been measured. Incorporating a detailed model description of the polarization effects and other target effects into a Monte Carlo simulation of the experiment, a good description of the various observables is obtained. In particular, the bond-angle distribution is found to agree with existing ab initio calculations.
