DEPTH PROFILING OF HYDROGEN IN SOLIDS BY ELASTIC RECOIL DETECTION WITH 19F IONS

  • The hydrogen depth profiling in solids has been done by elastic recoil detection (ERD) technique with multicharged 19F ion beam from a small Tandem Accelerator of 2x1.7MV. Details of the experimental technique are described. The depth resolution of about 230Å in the near-surface regions (~5000Å)is much better than that of ERD technique with 2.5MeV He beam and heavy ion beam of 30MeV.
