摘要: The photoionisation threshold region of homogeneous Argon and Krypton clusters Arn Krn forn up to 24 formed in a free jet expansion has been studied detail, using the photoelectron photoion coincidence (TPEPICO) time flight technique. Measurements performed at variety different conditions (nozzle temperature stagnation pressure) demonstrate that fragmentation larger contributes substantially shape TPEPICO spectra even for smallest all photon energies higher than about 200 meV 400 above ionisation threshold. determination potentials these cluster ions is discussed careful estimates are given compared with recent theoretical values.
