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 parameterfree numerical procedure. The measured angular distributions show large widths (> 50°) for all initial energies. In addition, final translational distributions show a large spread with a mean translational energy of about half the initial energy.
