摘要：

Results from measurements of the hydrogen uptake in Mo/V single-crystal superlattices with modulation wavelengths (LAMBDA) from 0.3 to 17.7 nm are presented. These studies were performed by hydrogen profiling, using the H-1(N-15, alpha-gamma)C-12 reaction, and x-ray diffraction. The average hydrogen to metal ratio was found to decrease for decreasing LAMBDA. For LAMBDA greater-than-or-equal-to 13 nm, large structural changes are observed, while for LAMBDA less-than-or-equal-to 5.5 nm no structural changes were observed upon hydrogenation. A model describing the modulated-wavelength dependence of the hydrogen uptake is proposed.
