The activation energy, H, the activation volume, w\*, and the frequency factor, Y, for the plastic deformation of niobium at low temperatures (T < 0.2 T,) were derived from creep tests. The values of H and e\* for r\* = 1 kg/mm2 were 0.75 eV and 47bS respectively, decreasing with increase in stress.
