Shooting polarized electron beam on a polarized target

Hi experts!

I have a general question. I would like to try and simulate a polarized electron beam to heat a polarized material, with a few % of the material to be polarized. I’m interested to see how the interaction of different polarizations will change the trajectory of the electrons. Can you please let me know if this is something possible to do, and if so to please direct me to the relevant packages? I did not find this possibility so far.

Best,

Yoav.

Dear experts,

This is a kind reminder for tis question.
