Mössbauer study of the modification of iron during bombardment with deuterium at low temperature

Mossbauer spectra of a vacuum deposited 95 nm thick57Fe film sandwiched between 35 nm copper layers on a beryllium substrate were measured during and after implantation with 60 keV D3 + ions to a fluence of 1.2×1018 D+/cm2. The modifications of the spectra indicate that at the target temperature of 100 K deuterium is mainly trapped at defects in the α-iron lattice or reemitted. Hydride formation is observed only weakly when the fluence exceeds 1018 D+/cm2. After annealing at room temperature, a complete recovery of the ordinary α-iron spectrum is observed.
