Fractal Core Shell Definition Calculates the scattering from a fractal structure with a primary building block of core-shell spheres, as opposed to just homogeneous spheres in the fractal model. It is an extension... Shape-Independent 07 Sep 2017 sasview 0
Core Shell Ellipsoid Definition Parameters for this model are the core axial ratio $X_{core}$ and a shell thickness $t_{shell}$, which are more often what we would like to determine and make the model better beha... Ellipsoid 07 Sep 2017 sasview 0
Mass Surface Fractal A number of natural and commercial processes form high-surface area materials as a result of the vapour-phase aggregation of primary particles. Examples of such materials include soots, aerosols... Shape-Independent 07 Sep 2017 sasview 0
Rpa .. warning:: This model is not functioning correctly in SasView and it appears it has not done so for some time. Whilst the problem is investigated, a workaround for Case ... Shape-Independent 07 Sep 2017 sasview 0
Stacked Disks Definition This model provides the form factor, $P(q)$, for stacked discs (tactoids) with a core/layer structure which is constructed itself as $P(q) S(Q)$ multiplying a $P(q)$ for individual... Cylinder 07 Sep 2017 sasview 0
Hayter Msa # Note: model title and parameter table are inserted automatically Calculates the interparticle structure factor for a system of charged, spheroidal, objects in a dielectric medium [1,2]. When comb... Structure Factor 07 Sep 2017 sasview 0
Broad Peak Definition This model calculates an empirical functional form for SAS data characterized by a broad scattering peak. Many SAS spectra are characterized by a broad peak even though they are fr... Shape-Independent 07 Sep 2017 sasview 0
Multilayer Vesicle Definition This model is a trivial extension of the core_shell_sphere function where the core is filled with solvent and is surrounded by $N$ shells of material (such as lipids) interleaved w... Sphere 07 Sep 2017 sasview 0
Stickyhardsphere # Note: model title and parameter table are inserted automatically Calculates the interparticle structure factor for a hard sphere fluid with a narrow, attractive, potential well. Unlike the `squar... Structure Factor 07 Sep 2017 sasview 0
Spherical Sld Definition Similarly to the onion, this model provides the form factor, $P(q)$, for a multi-shell sphere, where the interface between the each neighboring shells can be described by the error... Sphere 07 Sep 2017 sasview 0
Gauss Lorentz Gel This model calculates the scattering from a gel structure, but typically a physical rather than chemical network. It is modeled as a sum of a low-q exponential decay (which happens to give a functi... Shape-Independent 07 Sep 2017 sasview 0
Core Shell Bicelle Elliptical Definition This model provides the form factor for an elliptical cylinder with a core-shell scattering length density profile [#Onsager1949]_. Thus this is a variation of the core-shell bicel... Cylinder 07 Sep 2017 sasview 0

Adsorbed Layer Definition This model describes the scattering from a layer of surfactant or polymer adsorbed on large, smooth, notionally spherical particles under the conditions that (i) the particles (cor... Sphere 07 Sep 2017 sasview 0
Two Lorentzian Definition The scattering intensity $I(q)$ is calculated as $$ I(q) = \frac{A}{1 +(Q\xi_1)^n} + \frac{C}{1 +(Q\xi_2)^m} + \text{B} $$ where $A$ = Lorentzian scale factor #1, $C$ = Lorent... Shape-Independent 07 Sep 2017 sasview 0
Vesicle Definition This model provides the form factor, *P(q)*, for an unilamellar vesicle and is effectively identical to the hollow sphere reparameterized to be more intuitive for a vesicle and nor... Sphere 07 Sep 2017 sasview 0
Surface Fractal This model calculates the scattering from fractal-like aggregates based on the Mildner reference. Definition The scattering intensity $I(q)$ is calculated as $$ \begin{align*} I(q) = \... Shape-Independent 07 Sep 2017 sasview 0
