Abetract-The terminal solubility of hydrogen (TSH) in equilibrium with hydride in the Nb-Ta system is known to show a large intermediate maximum at temperatures in the region of 250 K. The origin of this "abnormal" behavior has not been successfully explained previously. In the temperature range of

Literature data for diffusion, internal friction, inelastic neutron scattering and specific heat for hydrogen in V, Nb and Ta are correlated with simple models for tunnelling. Tunnelling motion can occur through interference of tunnel-split excited states, or through two-phonon transitions via virtu
## Oxygen-Tantalum Interaction in Niobium This article deals with results of the investigation of oxygen dissolution in niobium foil containing tantalum impurity. Experimental data show spatial separation of oxygen and tantalum in niobium if the oxygen concentration is near to the oxygen solibilit
