# Gamma radioactive decay of anti-particles

Hello;

Just needed to clarify something. When anti-particles undergo gamma radioactive decay, is a gamma ray produced, or an anti-gamma ray? Or something completely different?

Thanks.

Photons (including gamma rays) do not have antiparticles. At a distance particle decay cannot be distinguished from antiparticle decay by spectral analysis.
