“…As for formulas (36) and (37), they are a consequence of the exact solution of the Schrödinger integral equation (9) and, therefore, are not in doubt. Compound potential barriers are accompanied by potential wells the bound states of which resonate with the incident wave.…”

The research is devoted to the problem of designing materials with an adjustable property of permeability. The obtained tool for property regulation allows achieving hyper-selectivity in relation to separation of helium isotope mixtures, as well as some other gas mixtures. The reasearch is theoretical in nature; however, it suggests a clear direction of activity for experimenters. The result obtained is valid for ultrathin barriers of any form. As a result, a new exact solution of the Schrödinger equation of wave dynamics, which is valid for the case of two-barrier systems, is found. This solution allows for comprehensive consideration of the process of wave passage through a barrier and identification of the causes leading to super-permeability of individual components.

“…Among the metals with potential to be used in fusion facilities, the refractory metals, niobium and tantalum, are very interesting materials for structural components [7]. For example, they are promising materials for the pumping panel in the divertor region [8], tube material in vacuum permeator for tritium recovery from Pb-17Li liquid blanket system [9], superpermeable membranes for selective hydrogen isotope exhaust [10].…”

Niobium and tantalum sheets were loaded with tritium and their superconducting properties were investigated. Superconductivity is rather robust in both materials though they belong to different types of superconductors. The critical temperature does not change in the case of Nb at low field but decreases slightly in the case of Ta. The tritiumloaded Nb shows a higher remanent magnetization which we attribute to the subsurface accumulation of defects, but the high field irreversible magnetization is smaller than for the bare sample. In the case of Ta, both the remanent magnetization and the irreversible magnetization are slightly reduced after tritiation.
