Abstract

A Kohn-Sham time-dependent local-density-functional scheme is utilized to predict attosecond time delays of xenon 4d photoionization that involves the 4d giant dipole resonance and Cooper minimum. The fundamental effect of electron correlations to uniquely determine the delay at both regions is demonstrated. In particular, for the giant dipole resonance, the delay underpins strong collective effect, emulating the recent prediction at C60 giant plasmon resonance [T. Barillot, Phys. Rev. A 91, 033413 (2015)PLRAAN1050-294710.1103/PhysRevA.91.033413]. For the Cooper minimum, a qualitative similarity with a photorecombination experiment near argon 3p minimum [S. B. Schoun, Phys. Rev. Lett. 112, 153001 (2014)PRLTAO0031-900710.1103/PhysRevLett.112.153001] is found. The result should encourage attosecond measurements of Xe 4d photoemission.
