Abstract

The ion-induced release of deuterium trapped in molybdenum at room temperature was investigated by subsequent bombardment with protons using incident energies ranging from 0.5 to 6 keV for deuterons and protons. The release curve of deuterium pre-implanted at 1 keV due to proton bombardment at energies from 1 to 6 keV consisted of two exponential decay curves. The two decay constants, i.e., release cross sections, decreased with increasing dose of the implanted deuterium. Two distinct peaks were observed in the release spectra of deuterium pre-implanted at energies from 3 to 6 keV due to proton bombardments at the corresponding energies. The release spectra and the amount of release of D2 were dependent on the implanted deuteron dose, deuteron energy, proton energy and condition of pre-implanted target. The results are discussed in view of radiation damage effects.
