N2 - Incoherent inelastic neutron scattering (IINS) measurements of the vibrational density of states (VDOS) of hydrogen trapped at dislocations in deformed PdH0.0013 have been performed using ARCS at the SNS and FANS at the NCNR. A comparison of data sets at 4 and 295 K indicates good agreement of the measured VDOS for the two instruments. The low hydrogen inventory (∼10-3 g) provides a test of the response of each instrument over the energy transfer range of 40100 meV corresponding to the vibrational density of states of the hydrogen modes.
