Summary We derive a low-energy theorem connecting the weak radiative decays α→β+γ and α→β+π+γ. By expanding in powers of the photon four-momentum we then express the amplitude for α→β+γ in terms of the nonleptonic process α→β+π. We calculate the decay rates and branching ratios for all possible hyperon two-body weak radiative decays.
