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
An electrochemical technique has been used to measure the diffusion coefficient of hydrogen in palladium-copper and palladium-niobium alloys between 0 and 50ยฐC. The range of concentration for the copper and niobium additions was 0-lOat.?.,. For all experiments the hydrogen content was kept below 0.1
