Description

Photoionization by an eXtreme UltraViolet (XUV) attosecond pulse train (APT) in the presence of an infrared pulse (RABBITT method) conveys information about the atomic photoionization delay. By taking the difference of the spectral delays between pairs of rare gases (Ar,He), (Kr,He) and (Ne,He) it is possible to eliminate in each case the larger group delay ('attochirp') associated with the APT itself and obtain the Ar, Kr and Ne Wigner delays referenced to model calculations of the He delay....[Show more]
