ResumoThe 1H NMR was observed in hydrogen chemisorbed K-GIC C8KH23 and the spin lattice relaxation rate T−11 of 1H was measured at the temperature range from 1.3 to 300 K. The temperature dependence of T−11 obeyed the T1T = const. law below 100 K and well characterized the metallic Fermi surface. Together with the observed small angular dependence of T−11, the existence of delocalized s-wave electrons on hydrogen was confirmed.
