ANGULAR AND TRANSLATIONAL ENERGY-DISTRIBUTIONS OF NO SCATTERED FROM PT(111)

Time of flight spectra and final angle distributions are measured for NO scattered from Pt(111) at thermal up to hyperthermal initial kinetic energies (0.1-2.5 eV). The time of flight averaging, due to the finite experimental resolution, is deconvoluted with a simple parameter-free numerical procedure. The measured angular distributions show large widths (> 50 degrees) for all initial energies. In addition, final translational distributions show a large spread with a mean translational energy of about half the initial energy.
