Question:
Does anti matter have spin? Is there a measurable change in spin? (ravel and eventually unravel?
Replies:
The difference between “matter” and “anti-matter” is the reversal of electrical charge on the electrons and the nuclei. Spins remain the same.

A change in electron spin can alter the energy of electronic states slightly, but that is not a conversion from “matter” to “anti-matter”.
