One of the obstacles in the control of atom-photon interfaces is the individual spontaneous emission of the atomic system, where the photons are scattered in any direction. But, in systems with coupling between atoms is possible to have a collective dissipation process, where the emission occurs along a specific direction. For the individual and collective dissipation of N two-level atoms, we obtained analytical solutions calculating a base of eigenvectors for the Lindblad operator of the evolution. To do so, we considering symmetry under particle exchange and a maximum in the total of atomic excitations. In particular, we calculated the fraction of energy dissipated through the collective process for some Dicke states, where we find that such a fraction is greater for states with less number of excitations.
