Metastable He*Atom?3ML Ag ? Cu (111) Surface Interaction by Using Wave Packet Propagation Method
Falah Hassan, Suha Hadi
Abstract: This research deals with the static metastable He* atom when interacts with C (111) surface and with this surface modification when Ag (i. e. noble metal) deposit on it as a thin film with 3 mono layers (3ML). This study gives the charge transvers process with Resonance Ionization (RI) theoretically by solve the time dependent Schrodinger equation (wave packet propagation method) with new surface potential, and show the dependence of charge transvers on the time interaction, particle- surface distance as well as the 3ML effects on this process. The results Shows that the density of state and the survival probability for pure Cu (111) metal and for Ag/Cu (111) and also show the wave function spreading on the surface. The results have good agreement with experimental results.
