""_1^0e + ""_text(-1)^0e -> gamma + gamma

Explanation:

This nuclear equation describes the electron-positron annihilation in which an electron collides with its antiparticle, a positron; the collision annihilates the electron and the positron and releases two gamma-ray photons.

A positron is the electron's antiparticle, i.e. a particle that has the same mass but opposite charge. When the two collide the resulting annihilation and gamma-ray photon emission are described by this equation:

""_1^0e + ""_text(-1)^0e -> gamma + gamma
