Fullerene photoemission time delay explores molecular cavity in attoseconds
Abstract
Photoelectron spectroscopy earlier probed oscillations in C60 valence emissions, producing series of minima whose energy separation depends on the molecular cavity. We show here that the quantum phase at these cavity minima exhibits variations from strong electron correlations in C60, causing rich structures in the emission time delay. Hence, these minima offer unique spectral zones to directly explore multielectron forces via attosecond RABITT interferometry not only in fullerenes, but also in clusters and nanostructures for which such minima are likely abundant.
