Abstract
In stage I Li-graphitide, we try to determine the nature of interactions between Li nuclear spins and their neighborhood by variable temperature measurements of the Li nuclear spin lattice relaxation time T1. Two methods are used: 7Li pulsed NMR; and β-radiation detection of 8Li-nuclear polarization produced by polarized neutron capture. Both methods are in qualitative agreement, but a quantitative discrepancy appears in the low-temperature range. Results are discussed in relation with several mechanisms: contact interaction and Korringa relation, quadrupolar mechanism and diffusion modulated dipolar interaction.
