摘要：
The procedure for calibrating the VESUVIO eV neutron spectrometer at the ISIS neutron source is described VESUVIO is used primarily to measure the momentum distribution n(p) of atoms by inelastic scattering of very high energy (5-150 eV) neutrons The results of the calibrations show that measurements of n(p) in atoms with masses lower than 16 amu can be measured with a resolution width similar to 25% of the intrinsic peak widths in the current instrument configuration Some suggestions as to how the instrument resolution could be significantly improved are made (C) 2010 Elsevier B V All rights reserved
