Photofragmentation of masshyphen;selected C+16to C+36clusters is investigated at two laser wavelengths: 532 and 355 nm. The depletion dependence on laser fluence leads to the number of absorbed photons, together with the photoabsorption cross section. From the knowledge of the internal energy deposited in the clusters before the fragmentation step, the dissociation energies are deduced. Clusters C+16to C+29are found to be less and less stable, whereas above C+30an increased stability is observed.
