TDPAC studies of the intercalation compound LixTiS2 in the region 0≤x≤1

The electrochemical intercalation of Li+ into hafnium-doped TiS2 was studied using time-differential perturbed angular correlations (TDPAC). The 181Ta nuclear quadrupole interaction was monitored as a function of the charge transfer, nF. For low uptakes, 0≤nF≤0.03, a two-phase region was found with an empty host interaction, characterized by νq=458(4) MHz, η=0.19(3) and δ=0.083(5), and a second interaction corresponding to lithiated material with νq=597(5) MHz, η=0.13(4) and δ=0.061(5). No evidence was found for intermediate phases. (orig.)
