The reaction that releases energy is called an EXOTHERMIC process. This is a word from the prefix exo- which means to exit and from the root word therm which is a unit of heat which in turn is form of energy. This is the opposite process of ENDOTHERMIC process.
Answer:
Particle-antiparticle annihilation is the result of a direct interaction between a particle and its corresponding anti particle, like a proton and an anti-proton or an electron and a positron. The result of such interaction is the production of two powerful gamma rays, each of whom has an energy roughly equal to E = mc^2, where m is the mass of the particle.
