Abstract

Bu çalışma, 10-14 Mayıs 2010 tarihleri arasında Beijing[Çin]’da düzenlenen 14. International Conference on Calorimetry in High Energy Physics (CALOR 2010)’da bildiri olarak sunulmuştur. The energy deposited in the active medium of the crystal fluctuates event by event. This fluctuations in the lateral shower containment contributes to the stochastic term. The lateral shower shape determines the distribution of the energy deposition in a cluster of crystals around the impact point. The contribution to the stochastic term coming from fluctuations in the lateral shower containment of calorimeter prototypes of PbWO4 crystals have been simulated by GEANT4 for incident electrons at different energies.

Abstract

We study size-selected deposition of Ag/sub 19//sup +/ clusters on Pd(100) at total kinetic energies of 20 and 95 eV using thermal energy atom scattering and molecular-dynamics simulations. Contrary to the case of Ag/sub 7/ where fragmentation is crucial to explain the data, the deposition leads at low temperature to noncompact structures localized around the impact point. We propose a model in which morphology changes take place between 200 and 300 K resulting in well-separated compact structures.
