7Li nuclear spin relaxation and electrical conductivity measurements were performed as a function of temperature for varying Li content in (1-x)GeO2:xLi2O glass series where x=0. 01 to 0. 36. Above room temperature the nuclear spin relaxation rate increases exponentially with rising temperature giving an activation energy ENMRwhich is always lower than the activation energy Eδfor dc conductivity. However, below x=0. 1 ENMRincreases rapidly with decreasing x and is found to approach Eδfor x approaching zero. The result is discussed in view of a motion of the Li ions correlated by Coulomb interaction.
