The initial value of sticking coefficient at negligible hydrogen uptake was ca. 0.25 and was independent of surface temperature. At any temperature examined, α showed a significant reduction with increase in hydrogen uptake, although the extent of reduction decreased with increasing temperature. Such reduction in α was ascribed to the increase in the surface coverage of hydrogen due to surface segregation and was explained by a model assuming equilibrium partitioning of hydrogen between the surface and the solid solution phase in the bulk., Article, 富山大学水素同位体科学研究センター研究報告 = Annual Report of Hydrogen Isotope Research Center, Toyama University 25, 25-39.(2005)}, pages = {25--39}, title = {清浄Nb表面への水素の吸着と偏析}, volume = {25}, year = {2005} }
