Abstract
We investigate the onset of photoionization shake-up-induced interatomic Coulombic decay (ICD) in He2 at the He+∗(n = 2) threshold by detecting two He+ ions in coincidence.We find this threshold to be shifted towards higher energies compared to the same threshold in the monomer. The shifted onset of ion pairs created by ICD is attributed to a recapture of the threshold photoelectron after the emission of the faster ICD electron.
