摘要
Tritium desorption isotherms and helium release properties are reported for three different LaNi4.25Al0.75 samples having seen 11.5 and 13 years of tritium exposure, and are compared to earlier data from similar samples with less exposure. The isotherms show a complete loss of the typical plateau structure, and a decreasing absorption capacity. However, the capacity loss is not due to further increase in heel content. Helium breakout is show to occur in one sample when the T content became low. (C) 2003 WSRC. Published by Elsevier B.V. All rights reserved.
