Potential models


potfit supports two very different ways of defining a potential. Both ways use some parameters $\alpha_i$ to define a potential, but they have very different meanings.

There are tabulated potentials and analytic potentials. The main differences are given in the table below.

tabulated potential analytic potential
  • Many parameters
  • Local parameters
  • arbitrary functions
  • few parameters
  • global parameters
  • physical meaning
