| Core Shell Sphere |
.. _core_shell_sphere:
This model provides the form factor, $P(q)$, for a spherical particle with a core-shell structure. The form factor is normalized by the particle volume.

# rectangular_prism model # Note: model title and parameter table are inserted automatically Definition
This model provides the form factor, $P(q)$, for a hollow rectangular prism with infinitely thin walls. It computes only the 1D scattering, no… |
| Mono Gauss Coil |
#mono_gauss_coil model #conversion of DebyeModel.py #converted by Steve King, Mar 2016 This Debye Gaussian coil model strictly describes the scattering from *monodisperse* polymer chains in theta solvents or polymer melts, conditions under which the… |

# pylint: disable=line-too-long
Elliptical cylinder geometry $a = r_\text{minor}$ and $\nu = r_\text{major} / r_\text{minor}$ is the *axis_ratio*.
The function calculated is
$$ I(\vec q)=\frac{1}{V_\text{cyl}}\int{d\psi}\int{d\phi… |

Definition
Scattering from spheres with a Gaussian interface.
The scattering intensity $I(q)$ is calculated as:
$$ I(q) = \frac{\text{scale}}… |
| Porod |
This model is a special case of the power law model, deriving its special name from the Porod Law which it models, where the power law exponent is fixed to -4.
$$ I(q) = C/q^4 + Background
$$
Where the power law constant $C$ in this case is just… |
| Guinier Porod |
Calculates the scattering for a generalized Guinier/power law object. This is an empirical model that can be used to determine the size and dimensionality of scattering objects, including asymmetric objects such as rods or platelets, and shapes inte… |
| Core Shell Cylinder |
Definition
The output of the 2D scattering intensity function for oriented core-shell cylinders is given by Kline [#Kline2006]_. The form factor is normalized by the particle volume. Note that in this model the shell envelops the entire core s… |
