Abstract

We study frustrated double ionization (FDI) in a strongly-driven heteronuclear molecule HeH+ and compare with H-2. We compute the probability distribution of the sum of the final kinetic energies of the nuclei for strongly-driven HeH+. We find that this distribution has more than one peak for strongly-driven HeH+, a feature we do not find to be present for strongly-driven H-2. Moreover, we compute the probability distribution of the principal quantum number n of FDI. We find that this distribution has several peaks for strongly-driven HeH+, while the respective distribution has one main peak and a 'shoulder' at lower principal quantum numbers n for strongly-driven H-2. Surprisingly, we find this feature to be a clear signature of the intertwined electron-nuclear motion.
