FIG. 1.

Schematic fragmentation pathway after ionization with photon of an argon atom in the cluster, where X stands for all possible neutral fragments. Note that no scattering of the photoelectron is considered in this scheme.

FIG. 2.

Mass spectra for cluster with 10 up to 1000 atoms at . The spectra are normalized with respect to the total number of electrons (starts) and to the acquisition time, so the intensity of each peak reflects the partial cross section of each photoion scaled by the detection probability. In the inset we present the log-normal distribution of neutral clusters for different cluster sizes on log-log scale in order to illustrate the general trend expected from simple XUV photoionization.

The and photoion peaks from Fig. 2 are shown using a solid line. The dashed line represents the line shape for the same ion measured in a double, triple, and quadruple ion-coincidence event.

Time of flight distribution of daughter ions for different lifetimes of the mother ion. The bold lines highlight which distributions are used for the comparison with the experiment and the scaling factors are added to give the relative peak heights. and represent, respectively, the mother and daughter time of flights if these ions were produced in the ionization volume without kinetic energy. For this simulation the , , 300, , and .

Table I.

Typical time scale associated with the decay of photoionic dimers and photoionic trimers in the mass spectrometer. For large clusters additional decay into dimer channel is given. The bold characters are used to specify which channel of observation are considered for the analysis.
