Abstract

The interaction energy of phonons in a Bose-Einstein condensate was directly measured by computerized tomography of TOF images. The measured energy agreed with the predicted Bogoliubov spectrum in the LDA. Hydrodynamic simulations of the release process were consistent with the experimental findings.
