The dynamics of formation of heavy-Rydberg ion-pair states throughelectron transferin K(np)-SF6, CCl4collisions is examined bymeasuringthevelocity,angular, and bindingenergydistributions of the product ion pairs. The results areanalyzedwith the aid of a Monte Carlo collision code that models both the initial electron capture and the subsequent evolution of the ion pairs. The model simulations are in good agreement with the experimental data and highlight the factors such asRydberg atomsize, the kineticenergyof relativemotionof theRydberg atomand target particle, and (in the case of attaching targets that dissociate) the energetics ofdissociationthat can be used to control the properties of the product ion-pair states
