The long delays measured in N2O are shown to reflect the population of molecular shape resonances that trap the photoelectron for a duration of up to ∼110 as. The setup consists of a gas cell for high-harmonic generation followed by a delay line that spatially separates and then recombines the extreme-ultraviolet (XUV) and residual infrared (IR) pulses. Here, an attosecond pulse generates photoelectrons on a sample, which at the same time is exposed to phase-stabilized and temporally synchronized near-infrared laser pulses.

Electron-spectroscopy — outlook. The ability to time electrons moving in solids over merely a few interatomic distances makes it possible to probe the solid-state electronic processes occurring at the ultimate speed limit and thus helps to advance technologies such as computation, data storage and photovoltaics, which all rely on exquisite control of electron transport in ever smaller structures of solid matter. 0000001116 00000 n Interface Anal. 0000001972 00000 n PHYSICAL REVIEW A 83, 033405 (2011) Theory of attosecond transient absorption spectroscopy of strong-field-generated ions Robin Santra,1 ,2 3 Vladislav S.
