Summary on Grant Application Form |

We propose a series of experiments which will be linked to the instrument developments funded by the EU under the VESUVIO project. 1) Experiments designed to measure the line shape of the momentum distribution in normal and superfluid bulk helium4. These will allow us to investigate the size of the Bose condensate fraction and the importance of final state corrections. They will provide a stringent test of the improvements of the eVS resolution function which will ensue from the instrument developments funded by VESUVIO.2) High accuracy measurements of the kinetic energy of He4 and He3 atoms; (a) through the superfluid transition in bulk He4 (b) In He3/He4 mixtures as a function of He3 concentration. (c) He4 in Vycor and Areogel glass through the superfluid transition. These measurements will be compared with advanced many body calculations and used to test improvements to instrument performance funded by VESUVIO.
