Evidence for the isotope effect on the liquid-liquid metal-insulator transition in dense fluid hydrogen

ORAL

Abstract

We report new results investigating the liquid-liquid metal-insulator transition in hydrogen. Previous investigations using dynamic compression techniques have focused on the deuterium isotope, while investigations with static techniques have examined both isotopes. We have fielded several dynamic compression experiments on the NIF with hydrogen and find clear evidence of an isotope effect in the pressure-temperature locus of the liquid-liquid metal-insulator transition. These results complement the recent static data and provide additional evidence to constrain theoretical models. LLNL-ABS-832655
