Dear Users Can anyone provide some help on the CoreShellBicelle Model (1D version) developed in SasView and referring to the documentation below? http://www.sasview.org/docs/user/models/model_functions.html#coreshellbicell... The following is not clear to me: 1) It is said that that the CoreShellBicelle Model is developed on the basis of the CoreShell Cylinder. I suppose that what it means is that if one squeezes a cylinder in its length (Radius>>Length), one obtains a bicelle morphology from a cylinder. However, in the Bicelle standard parameters, it is the contrary, Length (400)>>Radius(20). Is this normal? 2) In the CoreShellCylinder model, the Shell surrounds the Core in the axial direction, parallel to the length of the cylinder, as shown in http://www.sasview.org/docs/user/models/model_functions.html#coreshellcylind... Now, if I "squeeze" the cylinder in its length to make it a bicelle, I suppose that the shell will then correspond to the Rim Thickness of the bicelle. Is this correct? Or I did not figure this out at all in the rigth way and the Shell of the cylinder actually corresponds to the Face Thickness? Thank you very much for your help.
