[Sasview-users] CoreShellBicelle Model help
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.

In short, as I understand your questions the answer is yes. Actually there is no requirement that L>R. L is defined as along the axis and R is the radially symmetric dimension. Indeed with L>>R it would be considered a long rod while L<R would be a disc. Also you could have L=R. So the base of the bicelle is a disc. As for # 2 yes the rim is the shell around the axial dimension, while the face would be effectively another disc on each "face" of the disc Hope this helps Paul On Mon, Nov 30, 2015 at 1:58 PM, Niki BACCILE <niki.baccile@...16...> wrote:
