Computer Studies of D⁺-Ion Induced Atomic Displacement Rate and Deuterium Reemission Rate of Nickel with Absorbed Deuteriums

Abstract

The D ⁺ ion induced atomic displacement rate and reemission of energetic deuterons were analyzed by BCA-model calculations for nickel metal having absorbed deuterons on its surface, or containing absorbed deuterons in the bulk (NiD mixture). The results were compared with those for the pure nickel metal and the nickel oxide. The NiD mixture showed a large change in the D ⁺ projected range and the Ni atom displacement rate because of the influence of contained deuterons. The displacement rate of D atoms in the NiD was very large. The number of emitted D atoms from the D adsorbate layer on the Ni metal surface was about 30% at maximum of the total number of reflected D atoms.
