In this paper we are able to justify the existence or no of photons emittedduring $\alpha$ decay, based on the average half life times using the BCSsuperconductivity and superfluidity theories. The proposed model suggests twopossible channels. A first channel where the protons and neutrons interactseparately through a spin coupling, giving rise to diprotons and dineutronswhich in turn interact through an isospin coupling to form an $\alpha$particle, and a second channel where the protons and neutrons are treated asnucleons that interact through an isospin coupling, giving rise to deuterons,which in turn interact through a spin coupling to form an $\alpha$ particle.Due to the nature of the involved particles, the systems considered arehomogeneous. For the second channel, the photon play a very important role forthe possible escape of the $\alpha$ particle. Within these premises the halflife times of a considerable number of heavy nuclei with spherical symmetry canbe estimated with good experimental agreement.
