Simulation of a scattering curve from a cylindrical core-shell model

In the following we calculate the scattering curve of a cylindrical shell model with an axially inhomogeneous (layered) core which might be a possible structural model for the LDL-molecule. The dimensions, radial and axial electron densities are shown in the following picture (cylindrical core-shell model with an axial cut through the cylindrical shell) below:

The parameter for this model are entered as input into the scattering curve simulator as shown below:




The resulting scattering curve I(q) in a lin-log plot from q = 0 to 2.5 [1/nm]:


The p(r)-function (Dmax = 31.4 nm) was calculated from this scattering curve using the program GIFT (O.Glatter):


I(q) and p(r) functions were also calculated using the program SINGLEBODY (G.Popovski):





I(q) and p(r) functions were also calculated using the program Shape2SAS (A.H.Larsen). Note, here units of the model, of I(q) and p(r) are in Å and 1/Å, respectively:
