The atoms in solid helium are weakly bound and have small mass so that the overlap of their wave functions (zero point motion) is large, making it a quantum solid close to the melting curve. The properties peculiar to quantum solids remain to be discovered. In liquid helium and metals the quantum statistics resulting from this wave function overlap yield superfluidity and superconductivity. Previous neutron scattering studies have established the broad outline of the excitation spectrum at two temperatures and one density, but questions remain, in particular for low energy transfers (and low momentum transfers), and we aim to address this region of phase space in this proposal. We wish to investigate the temperature and density dependence in more detail.
