Description

We study photoionization time delays in Xe in the 70-100 eV range by combining attosecond interferometry with coincidence spectroscopy. Supported by calculations using the relativistic random phase approximation, we identify two interfering ionization processes: the giant dipole resonance due to collective effects in 4d to continuum f excitation with a fast decay time of a few tens of attoseconds and a narrow resonance at threshold induced by spin-flip transitions, with much longer decay time of several hundreds attoseconds. Our results provide new insight into the complex electron-spin dynamics of photo-induced phenomena.

The dataset includes the recorded electron time of flight (seqxx.csv) and electron kinetic energy (seqxxe.csv) for each laser shot. Scan01, 03, 04, 06, 07 is RABBIT scan in Xenon and Scan 02, 05 is RABBIT scan in Neon.
