 Intense laser fields induce strong ionization in atoms and nanoclusters, resulting in high charge densities that lead to coulomb explosion and emission of highly charged ions. However, it is possible to generate negative ions with energy and ion yield approaching that of positive ions in a dense cluster ensemble using atomic species of positive electron affinity. The process behind this strong charge reduction involves the formation of ribogue excited clusters around the focal volume, which facilitates orders of magnitudes more efficient electron transfer. This phenomenon is explained by an active role of laser heated electrons and involves charged transfer reactions that are insufficient to explain the observations. This article was offered by R.
