The H atom transfer reaction in electronically excited
clusters is studied in
pump-probe experiments with femtosecond laser pulses. By applying
different probe photon energies we are able to detect the
dissociation products
for n = 1–6. Furthermore we show that the analysis of the corresponding ion
signals is not distorted by contributions from larger cluster ions due
to evaporation of
molecules. The formation times
of the products are ca. 140~ps for n=2–4 and about 80~ps for
n=5,6.
