Heteronuclear Limit of Strong-Field Ionization: Fragmentation of HeH${}^{+}$ by Intense Ultrashort Laser Pulses

P. Wustelt, F. Oppermann, Lun Yue +6

The laser-induced fragmentation dynamics of this most fundamental polar molecule HeH${}^{+}$ are measured using an ion beam of helium hydride and an isotopologue at various wavelengths…
