Abstract
The authors use velocity-map imaging following Coulomb explosion of doubly ionized alkali homodimers on the surface of a helium nanodroplet to map out the distribution of internuclear distances in both the ground and lowest triplet state. They find that the distributions are generally broader than the internuclear wave function, which they attribute to resonance effects in the initial multiphoton ionization of the dimer and interaction of the ions with the He droplet.
