Attosecond Time Delay in Photoemission and Electron Scattering near Threshold

Kheifets, Anatoli; Bray, Alexander; Bray, Igor


We study the time delay in the primary photoemission channel near the opening of an additional channel and compare it with the Wigner time delay in elastic scattering of the photoelectron near the corresponding inelastic threshold. The photoemission time delay near threshold is significantly enhanced, to a measurable 40 as, in comparison to the corresponding elastic scattering delay. The enhancement is due to the different lowest order of interelectron interaction coupling the primary and...[Show more]
