Description
The helium hydride molecular ion, HeH+, is the simplest heteronuclear
polar molecule and serves as a benchmark system for the investigation of
multi-electron molecules and molecules with a permanent dipole. We
specifically address the question: How does the permanent dipole of HeH+
affect the fragmentation dynamics in intense ultrashort laser pulses? We
study the laser induced laser-induced fragmentation; including
non-ionizing dissociation, single ionization and double ionization; of
an ion beam of helium hydride and an isotopologue at various wavelengths
and intensities. These results are interpreted using reduced
dimensionality solutions to the time-dependent Schrödinger equation and
with simulations based on Dressed surface hopping.
