[en] We present a novel method for determining the angular dependence of molecular photoionization, by measuring time-dependent ionization yields from transiently aligned molecules. This method allows us to map the angular dependence of nondissociative singlephoton ionization for molecules (N₂ and CO₂) for the first time. Knowledge of the angular dependence of molecular ionization cross sections is fundamental to basic molecular physics as well as being relevant to strong-field physics. However, the ability to directly measure the angular dependence of ionization in free molecules has been very limited. By combining intense femtosecond laser pulses to transiently align a molecular sample, with few-femtosecond high harmonic extreme-ultraviolet (EUV) pulses, a new capability arises for directly measuring the angular dependence of molecular single-photon ionization. They present the first experimental determination of the angular dependence of nondissociative single photon ionization. Theu use femtosecond EUV pulses to measure the yield of single-photon non-dissociative molecular ionization as a function of time (angle) as a molecule is undergoing field-free alignment. They present results for N₂ and CO₂.
