Experiments in high energy have reported hard collisions of point like particle electrons. Spin angular momentum is suggesting the electron has geometry larger than a point.
Scattering of photons by electrons has been reported in experiments and described in models. Can that data be interpreted to give geometry to electrons? Sometimes an equivalent diameter is found in proposals.
With a spin magnetic moment the choices are a distributed charge rotating around the spin axis, or a single charge causing wobble in the magnetic field.
Is The Electron Composed Of Three Parts With Fractional Charges And Differing Only In Something like Quantum Color?
