An investigation of solid solutions of hydrogen in thulium at low temperature and of their behaviour under electron irradiation

Abstract
The electrical resistivity of alpha phase solid solutions Tm(H,D)x, with 0.005N, while the defects themselves recover in the region of the anomaly. A model is proposed implying a H-H (D-D) pair configuration as the stable low-temperature form, with a concentration- and isotope-mass dependent binding energy. These pairs are broken up under irradiation giving isolated atoms with a higher contribution to electrical resistivity. The latter form again into pairs just below the anomaly, where they are afterwards dissociated thermally.
