If I placed and electron and a positron at a certain distance apart in a vaccumm, they would attract each other and annihilate producing 2 or more gamma rays. But, what I would like to know is, does the electron and positron emit photons as they are attracted towards each other before they annihilate ?
I am not refering to the virtual photons that are exchanged as they are attracted to each other. I am asking if real photons are emitted by either or both particles as they move towards each other.
An electron will emit photons as it moves towards the nucleus of an atom and drops down the energy levels, but in this case the electron is losing energy in the form of a photon emission. Does the electron and positron lose any energy during their attraction ?
