Abstract
The lifetime of interatomic Coulombic decay (ICD) [L. S. Cederbaum et al., Phys. Rev. Lett. 79, 4778 (1997)] in is determined via an extreme ultraviolet pump-probe experiment at the Free-Electron Laser in Hamburg. The pump pulse creates a inner-shell vacancy in one of the two Ne atoms, whereupon the ionized dimer undergoes ICD resulting in a repulsive state, which is probed with a second pulse, removing a further electron. The yield of coincident pairs is recorded as a function of the pump-probe delay, allowing us to deduce the ICD lifetime of the state to be , in agreement with quantum calculations.
