Models the Q dependence of the QENS line width (Gamma (hwhm)), diffusion coefficients (D), residence times (tau) and jump lengths (length) to extract the associated long range diffusive motions of molecules.
The Chudley-Elliot Jump diffusion model [1] has the form:
| Name | Default | Description |
|---|---|---|
| Tau | 1.0 | Residence time |
| L | 1.5 | Jump length |
