“…[30] Prior to the Kramers-Kronig analysis the measured spectra were corrected by substracting contributions of multiple scattering and eliminating the contribution of the direct beam by fitting the plasmon peak with a model function, which gives the low energy tail to zero energy for the loss function. [24] We note that in our case the quasi elastic background does not alter the plasmon position as discribed in [31][32][33]. …”

Preliminary study of electron‐energy‐loss spectra of YBa2 Cu3O7−δ

“…For the case of p2+q transitions, all combinations of Da.v.z+d7 ,X -Y2 are allowed to varying degrees. This case is therefore not as simple as the s-+p scattering, which requires the transferred wave vector q to be parallel to the final pstate (Chen and Silcox, 1977;Leapman et al, 1983).…”
