Abstract

A new analysis technique using high-energy helium ions for the simultaneous elastic recoil detection of all three hydrogen isotopes in metal hydride systems extending to depths of several μm's is presented. Analysis shows that it is possible to separate each hydrogen isotope in a heavy matrix such as erbium to depths of 5 μm using incident 11.48 MeV 4He ions with a detection system composed of a range foil and ΔE - E telescope detector. Newly measured cross-sections for the elastic recoil scattering of 4He ions from protons and deuterons are presented in the energy range 10-11.75 MeV for the laboratory recoil angle of 30°.
