Electron-Positron Attraction: How Do These Particles Interact?

[benk99nenm312]

I have been doing some thinking and I can't find the answer to my question anywhere, so I was wondering if someone else knew.

My question is simply this: Do electrons and positrons attract each other electromagnetically, or do the antimatter properties of the positron alter the interaction in some way?

The attraction is electromagnetic (positive & negative charges). The matter-antimatter effect is at the actual collision, mutual anihillation leading to a pair of 511 kev gamma rays.

I can confirm that electrons and positrons do indeed attract each other electromagnetically. This is due to their opposite charges - electrons have a negative charge while positrons have a positive charge. The antimatter properties of the positron do not alter this interaction, as the electromagnetic force is independent of the type of particle involved. In fact, the positron is often referred to as the antiparticle of the electron because of their identical properties, except for their opposite charges. This means that they will interact in the same way as any other positively and negatively charged particles. I hope this helps answer your question.
