Index of refraction, polarizability, and equation of state of solid molecular hydrogen

Abstract
The index of refraction and the equation of state (EOS) of hydrogen have been measured to high pressures, leading to a determination of the pressure dependence of the polarizability to greater than 1 mbar. A simple method for measuring the index allows for straightforward extension of both the index and EOS measurements to the highest pressures achievable in a diamond-anvil cell.
