Some other members of the sasview coding team have already had some thoughts in this direction .

Bu t since you are now the third person in the last 6 months to have asked for such a model, maybe it is about time we provided one! I will ‘ticket’ t he requirement… In the meantime, the only fitting program I know with such a model is Olivi er Tache’s pySAXS. But it is not the most straightforward program to use.

I study carbon nanotubes dispersions stabilized with dispersants using SANS . I am looking for a model similar to the idea of "core_multi_shell" but for a cylinder instead of a sphere. I need a cylinder with a core and 2 concent ric shells, each shell has its own SLD. Are you familiar with such a model? I've looked in the search engine and in the marketplace but could not find such a model. Best, Irena Levin -------------- next part -------------- An HTML attachment was scrubbed...
