FIG. 5.

Short time recombination fractions of (triangle) and (circle) showing symmetry in data due to identical pump∕probe wavelengths. Coherence peak at due to enhancement of two-photon background. Rising signal delayed by and .

FIG. 7.

The (closed circle) and (open circle) recombination fractions as a function of time following excitation to the state. The solid line represents a single-exponential fit which nicely describes both data sets and yields a recombination time of . The data exhibit more noise due to very low ion signals.

One-photon (Ref. 47) (pump only) and expected two-photon (pump∕probe) ionic products for selected clusters, following excitation. Only significant ( of total) secondary products are shown. For each parent cluster size, those secondary products recorded in our experiments and used for determination of recombination time scales are shown in bold.
