High energy resolution density fluctuations spectrum in 4He hcp
Our recent successful measurement performed last December on IN5 of the density fluctuation spectrum of a single crystal of 4He at moderate energy resolution demonstrates the great interest of measuring the dynamic of such quantum crystal where anharmonicity plays a crucial role. The full vision of the reciprocal space allowed by the IN5 instrument constitutes a formidable tool to investigate this dynamics. In the proposed experiment we plan to extends the previous measurements with a higher energy resolution for the low energy range. Both measurements will compose a set of data of invaluable quality to tackle mysteries such as the supersolidity in this material.
