Abstract

A high purity Cu target foil doped with 57Co and cooled to 80 K has been deuteron irradiated (E = 2 MeV to .5 MeV) using a Van de Graaff accelerator. In-situ Mössbauer spectra of the target were taken as a function of deuterium dose and post irradiation annealing. Two new 57Co sites are observed in addition to the original substitutional site. The new site ‘1’, populated at low temperature following the irradiations is identified with a 57Co impurity atom having Cu-interstitials trapped in its immediate vicinity. The new site ‘2’, populated on annealing the target above 360 K is believed to represent a 57Co impurity having deuterium localized in its vicinity.
