Figure 4
Energy-loss scans of La2CuO4 taken with the new instrument (filled circles) together with older data taken at 400 meV resolution in the same sample, at the same incident energy (empty circles). Data were taken at the (3,0,0) zone center wavevector with an incident energy of 8991 eV. Several new features are observed in the new data as a result of the improved resolution. The new data have a background of <1 count min−1 and a resolution of 130 meV. The data have been offset for clarity and scaled to have unit intensity. |
