An investigation of laser desorption by PIXE and RBS techniques

Journal Article

Gold atoms have been implanted at 1 and 30 keV energies in various substrates. Pulses from a Nd:YAG laser were used to desorb these atoms. Following laser bombardments, PIXE and RBS (Rutherford backscattering) measurements were performed, using the 3 MeV α beam of the Van de Graaff accelerator at the University of Montreal. These measurements reveal the quantity of Au extracted as a function of laser energy and show the migration of Au within the substrates. The results are compared with a simple diffusion model. © 1990.
