I thought that when positrons and electrons collide they annihilate straight away, giving up energy in forms of photons and other particles. However, I'm reading through some notes and they suggest that the positron loses energy rapidily in collisions with electrons but does not annihilate until it has slowed down sufficiently.
Is this correct, why does the positron lose energy so rapidly in collisions but not annihilate straight away?
Thanks
