Deuterium diffusion, trapping and release in ion-implanted nickel

A series of implantation/thermal release experiments has been performed on deuterium-implanted poly-crystalline nickel which had been pre-implanted with He+], B+], C+], O+] or Ni+] ions. The deuterium was implanted at 180 K: the amount retained and its approximate depth distribution were determined by periodic nuclear reaction analysis (NRA) during thermal ramping of the samples. The retention vs. temperature data were compared to calculations …
