摘要：

The electric conductivity of lithium compressed by dynamic methods by a factor of similar to 3 to 60 GPa pressure is measured. It is shown that the anomalous, by more than an order of magnitude with respect to the value under normal condition, decrease of electric conductivity under the experimental conditions is due primarily to the change in the interatomic distance. The results obtained can be explained on the basis of the hypothesis that a molecular structure is formed in the lithium at high pressure. (C) 1999 American Institute of Physics.
