摘要：

Photoionization and -fragmentation of Na(NH3)(n) clusters by 170 fs and 8 ns laser pulses are studied with photon energies of 2.98 eV to 3.46 eV. In the reflectron time-of-flight mass spectra a strong metastable loss of NH3 is observed independent of the laser pulse length. From the fragmentation rate constants the internal energy of the cluster ions prior to the fragmentation process is determined by an RRK approach.
