Abstract
The photodissociation of HCl on MgO(001) is studied by classical and q uantum methods. The quantum aspect resulting from the hydrogen zero-po int motion is also modeled in the classical simulation and has an impo rtant influence on the dynamics through the initial distribution of ti lt angles from the surface normal, The angular distribution of the sca ttered photofragments and the kinetic energy release of hydrogen show characteristic structures due to rainbows, scattering shadow and reson ances. Information about surface potential and adsorbate geometry can be obtained from them.
