Abstract
Experimental investigation of lithium compressed by multiple
shock waves up to
the pressure 210 GPa demonstrates the abnormal dependence of electric
resistivity. As
against normal behavior of metal, the resistivity monotonically
increases in the
pressure range 30-150 GPa from typical metallic value at ambient
conditions in more
than 15 times, returning back to metallic one at pressure higher then
160-210 GPa.
The obtained results demonstrate anomalous resistivity of lithium both
in solid in
liquid states.
