The 62.5 eV transient absorption feature in LiF is attributed to NIR coupling between the 1s2p bright exciton and an s-like dark exciton, and this coupling is suppressed when the pump and probe polarizations are crossed.
First the parameters of the bright states are extracted by fitting the experimental XUV- only linear absorption spectrum in the 60-64 eV energy range

Polarization-Resolved Core Exciton Dynamics in LiF Using Attosecond Transient Absorption Spectroscopy
The 62.5 eV transient absorption feature in LiF is attributed to NIR coupling between the 1s2p bright exciton and an s-like dark exciton, and this coupling is suppressed when the pump and probe polarizations are crossed.
