HallRossSQE¶
Description¶
This fitting function models the dynamic structure factor for a particle undergoing jump diffusion using the Hall-Ross Jump diffusion model [1].
where:
- Intensity scaling, a fit parameter - Centre of peak, a fit parameter - Residence time, a fit parameter - Jump lengths, a fit parameter - Momentum transfer, an attribute (non-fitting)
