The photodisintegration of the α-particle and more specifically the 4He(γ,p)3H and the 4He(γ,n)3He reactions, have been at the center of theoretical as well as experimental studies since the early fifties. Various aspects of the problem will be discussed. A brief historical overview of the experimental and theoretical controversies surrounding the photoneutron and photoproton cross-sections in the low energy region will be presented. Results obtained by means of the integral (momentum space) and integrodifferential (configuration space) equations will be given.
