Short-Wavelength Collective Excitations in Liquid and Solid Hydrogen
Abstract
Intermolecular and second-order light scattering in the condensed phases of hydrogen at para concentrations ranging from 25% to 96% have demonstrated the existence of underdamped short-wavelength collective excitations in the liquid phase over this concentration range and their relation to phonon excitations in the solid.
