Wj. Evans et If. Silvera, INDEX OF REFRACTION, POLARIZABILITY, AND EQUATION OF STATE OF SOLID MOLECULAR-HYDROGEN, Physical review. B, Condensed matter, 57(22), 1998, pp. 14105-14109
The index of refraction and the equation of state (EOS) of hydrogen ha
ve been measured to high pressures, leading to a determination of the
pressure dependence of the polarizability to greater than 1 mbar. A si
mple method for measuring the index allows for straightforward extensi
on of both the index and EOS measurements to the highest pressures ach
ievable in a diamond-anvil cell.
